A/C for chickens

Today I am so grateful for air conditioning. The weather is oppressively humid and hot. What can I do to help my chickens get through the next few days?

This is my makeshift air cooler. The gallon milk jug is solid ice, and I've placed it in a bucket (red, of course) of water. It's up on blocks which will absorb a bit of condensation as it melts. I have two more jugs of ice in the freezer to rotate as necessary.

We also have a fan in the coop. The girls don't appreciate the air blowing directly at them, so the fan is wired up at shoulder height and aimed into the hen house. Sorry that the photo is foggy, but the dew point is so high that I couldn't get the camera lens to clear.

In addition, I'll be hosing down the chicken yard every few hours and providing plenty of fresh water. To be honest, I worry more about the girls in the heat than I do in the sub-zero temperatures of January!

Sub-zero Chickens

Earlier this month we experienced three consecutive days of -20 degree Fahrenheit daytime temperatures. Although I believe chickens to be outdoor animals, that was just too cold for my hens to keep each other warm. So they came indoors to the basement bathroom for a few days. It was more than a circus!

A five pound hen generates about 10 watts of energy, so a flock of birds can usually warm each other, especially if they're in a barn with other farm animals. But our little flock of urban birds needed a bit of extra help.

This week we're heading into another polar plunge, but this time we're ready for it. We've installed two ceramic infrared heat emitters in the ceiling of the hen house. (We have no hope of keeping the entire coop warm because it's too large---6 x 8 feet and 7 feet high. But the raised hen house is only 3 x 6 feet and about 3 feet high.) These heat emitters do not emit any light. We've tried using red heat lamps, but it keeps our girls up and chattering all night long and sometimes drives them right out of the hen house. The ceramic heat emitters will keep the air temperature just marginally warmer than the outdoor temps. This is good enough for us, because we don't think it's entirely helpful to raise the temperature too much.

Ceramic heat emitters are designed for reptile pets. Many thanks to Ellen and David for pointing us in this direction!

Apiary Meltdown

We experienced a disaster in the bee yard at Red Bucket Farm. Due to extreme heat in the first week of July (over 100 degrees for three consecutive days), we discovered that all the combs in the red hive had melted off the top bars and dropped to the floor of the hive, crushing hundreds or thousands of bees. This was our newest hive and it had been doing fabulously, building a dozen combs, laying eggs, tending brood, bringing in nectar and pollen.

Last weekend (July 14) we cleaned out the melted mess from the floor of the hive. The combs had not melted off the top bars. In fact, there was still an inch or two of comb attached to each top bar, but the bulk of the comb had dropped in the heat. I remember a day in the extreme heat (when I was preoccupied with trying to keep the chickens alive) that there were suddenly a large number of bees on the outside of that hive. At the time I assumed it was normal bearding behavior in the heat, but in retrospect I believe the returning forager bees clustered outside because of the disaster inside.

We also discovered bees building comb in the roof of that hive. This was new comb without honey or brood, so we suspect they began building there after the meltdown. I have to admire their work ethic and resourcefulness.

After cleaning up the disaster, we shook the bees out of the rooftop and back into the hive body, then replaced all the top bars and let the bees get back to work. We're rebuilding the rooftop to repair the warp and prevent them from accessing the space. We also built an arbor-like structure over the bee yard and sewed awnings to provide some shade from the summer sun. The awnings can be removed in the fall when the sunshine will be beneficial to the hives.

We're concerned that it's rather late in the summer for that hive to rebuild enough that it will be strong for winter survival. This morning we took two top bars from an adjacent healthy hive to share with the struggling colony. The borrowed combs were full of honey, brood and bees. Perhaps this will jump-start the red hive for a chance at survival. If the queen was lost in the disaster, they may be able to groom a new one.  We're also providing supplemental cups of honey.

There is some good news. One of the hives is quite strong. We harvested 20 cups of honey which we can use to feed the weaker hive. Maybe there will even be some honey for us to enjoy. It's been a fascinating journey. There is nothing like an emergency to teach us about bee life.

Heat Exhausted Hens

It's been a brutally hot week here in the upper Midwest, over 100 degrees Fahrenheit for days. My four hens have done reasonably well in the heat by scratching wallows in the dirt and staying in the shade.

Last night the heat was unrelenting, still over 90 degrees at 10 pm. We placed a fan outside the hen house, hoping that a little breeze would provide some relief. Squill (the Speckled Sussex) was panting so fast and loudly that she may not have gotten any rest.  

This morning (a mere 80 degrees at 7:30 am) Squill was showing distress. She was panting loud and fast, stopping only to open her beak wide and gulp for air. By 10 am I couldn't risk it anymore. I brought the girls inside and settled them on the cool tile floor of the basement bathroom. They have food, water, and a couple of garden trugs with hay. They're resting quietly in relative darkness. Let's hope the poor things survive the summer.
