I went to check on my chickens this morning and noticed that my Houdan hen was missing feathers. At first I thought my other hen was picking on her since I just recently bought this hen, but then I saw that there were feathers stuck to our red heat lamp. Apparently, my husband either put the heat lamp too close to the chickens or my hen wanted to be super close to the heat. Probably a mixture of both. Now, I am worried if my hen will be okay. She is acting fine and I don't really see any blood. I turned the heat lamp off and won't be turning it back on, at least with that bulb. I learned my lesson. We just thought since the low last night was 4 degrees that we better give them some heat. Please let me know what you think from the photo. I really don't know what I could do now that it's already happened. The high today is 10 degrees here and will get down to 4 degrees again tonight. Their coop has plastic sheeting all the way around it with a few areas that air circulates through. Should we replace the bulb with a regular light bulb or no heat source at all? They have hay and pine shavings in their coop. Please be aware that I only have two hens and they don't even sleep close together, they have their own spots. They decided that that wanted out of their coop today to roam my yard which amazes me since their coop is a lot warmer than outside, especially since this one hen has less feathers now.
