I know everyone has a different opinion about when they are OK without them and of course temperatures outside play into that. I can't even remember when we took the heat lamp away from our hens, it's been two years. I feel like such a first time chick mom sometimes. But I also got them later in the year. I got our first hens two years ago at the end of Feb so by the time they were a month old, it was spring and there were no more cold nights. It's still pretty cold here at night so I don't think I'll be taking it away at night anytime soon but what about days? We are in TN on warm sunny 60 days, can they go without it for a few hours to begin adjusting to life without it? They are all fully feathered except their heads. They will be 1 month old Thursday. Should I start trying to slowly wean them off it next week, weather permitting?
