experiment in alternative heating

If there is frost on the windows inside the coop, I'd seek an alternate approach. I think it may be too humid and less good for the birds. have you tried hot water jugs for them?

 

Well I hope it works. I have had a 250 watt heat light outside on a timer. It comes on at 4 am and off at 4 pm. I have started keeping the chickens and turkeys in till the day temp gets close to 20 degrees due to the frostbite on my roo. On the nights it is dropping into the single digits I am keeping the light on all night. I am also keeping bag balm on the roos comb and wattles.

 

Liz, Your house air is prob pretty dry unless you have a humdifier running. I would say pretty confidently your doing fine running your house air into the coop. G/L

 

I don't know--chickens are more likely to get frostbite when the humidity is up (same process putting frost on your inside windows). Keeping the humidity down can be more important than keeping it warmer. I am not familiar with such cold temps, so hopefully some AKs or other northerners will weigh in...

 

Might help to further insulate the feed duct from the house. Anything you can find can work. Might try piling a couple of feet thick layer of leaves or hay or straw on the duct. That way more heat will reach the coop area. Carpet padding would work too. Maybe scrap carpeting or whatever then lots of leaves. Best to put some plastic over the leaves to keep them dry too.

 

Ice on the windows does not mean the humidity is up. It means there is a large enought temp difrence between inside an out to couse condensation.

 

I am using a small heater from Lowes that has a thermostat on it. It keeps the coop at a steady temp without having to wonder if they're getting too cold, too humid, etc. It has a heating element and small fan recessed behind a grate that would not let chickens anywhere close to the element. I hung it up about 24" above their heads and it's working beautifully. I don't need any illness due to cold when that's a factor I can control.

 

Good luck!
I too think the frost on the windows is more from condensation because of the heat differential. The heat duct from the house sounds easier than water bottles and more cost effective than electric heaters.

Our forecast is for -15F tonight.. Our 12 EE Pullets are 2.5 months old and still in the house! They are moving outside within the week. Their coop is almost done. Insulated like a cold climate house. R38 ceiling, R19 walls. Having a heck of a time getting the door to be tight so ice does not build up. I just want the coop to stay in the 20's or low 30's which is 45 degrees warmer than the outside air!
