I have spoiled or wrecked my chickens since they were born. As soon as it started getting cold her I put the red heat lamps on them high enough that they couldn't get hurt. Every morning when I go out they are not under the lamps but I felt better giving them some heat. I have noticed some black spots on some of the girls but mostly on the rooster on his waddle. Felt terrible that I was the cause of this so last night after reading everyone's posts on the minus degree weather you all have and never use the heat lamps, I didn't turn mine on last night. Worried about them although the temp wasn't that cold, still in the 20's. They survived and I guess I did to although I didn't get much sleep from worrying about them. We are all alive and doing well so guess I have you all to thank for drumming it into this thick skull that CHICKENS can survive in the colder weather. THANKS for making me think.
