I just turned on my heat lamp 2 days ago. Both last night and the night, when I went outside around 10pm I noticed that most of my chickens were not sleeping. They were roosted but awake. Some were sleeping but, others had their heads up and looking around.
Last winter was my first with chickens. I used the heat lamp last year also. I also wound up with a horrible case of feather picking by spring. Right now everybody has just finished coming back into feather after molt and, all but one, look great. I thought my feather picking was due to overcrowding since they just didn't want to leave the coop, not even to go out to the run. This winter I have 2 less chickens and really don't believe they are overcrowded.(more than 4sq'/bird) I am now wondering if the red heat lamp bulb is affecting their sleep?
I've read on here many times it usually doesn't so, gave it a try. How many people have had issues using red heat lamp bulbs to warm their chickens/coop?
I keep mine up quite high, above and in front of their roosts. High enough that they cannot reach the lamp but, low enough that some heat makes it down to the roosts.
BTW, I was horribly against providing any heat for them for the "what if" reasons. But, I noticed them huddled together, in their coop, all day, hardly moving. Even when I would go into the coop they'd move, as a group to the other end, a whole 6' and avoid going outside. I just couldn't watch them suffer. After I put the lamp on they were more inclined to move about inside the coop so I believe I lessened their suffering. I totally agree they "should" be able to survive without. Next time I hope I get some heartier chickens!
