We just moved. I got my 11 hens settled Jan 4th in their "new" coop. I was a little worried about the cold weather because their old coop was insulated and this one isn't so I put a heat lamp. It was on for a week and a half and then I switched it to just a red bulb. I did that because I noticed that they were laying more eggs than normal and I was worried that the light was stimulating them too much. Then, just a few days ago, I turned it off completely because I was still getting a lot more eggs per day than before. Do you think all this light changing is bad for them? How do you give your hens (if you do) a little extra heat without light?
