I have 4 week old babies, nicely feathered out. We live in TX. Generally in the 60s-70s daytime and 40s-50s in the night. We do have a couple days of 29 degree nights coming up. I am ready for them to move to the coop due to smell, mess, and making me stuffy. They have been off heat for a week as they are in my living room and it's been 65-72 in the house. I observed them not sleeping or using the heat provided, so I removed it. I observe them all day and they are doing wonderfully, not cold or anything. That said, would they be ready to move outside already? After the 2 day cold front? I am probably going to let them in the coop during the days and then bring them in at night for a bit. BUT will probably observe how they do. I am a firm believer in treating the as a mam hen would. They were raised with a heating cave, temps were not exact and dropped exactly 5 degrees each week. I watched carefully and adjusted it to where I felt they needed it. I don't feel like a mam hen would drop her temp 5 degrees each week. They just dart in and out from under as needed. I mean there are mama hens raising them out in snow and they are fine...others born in coops colder than mine. So I want to hear from others that either never keep them inside or move them at this age...or earlier. I personally feel they will be fine, BUT there is that little voice that questions every so often. Maybe because it's a big change. @blooie - any advice?? I love your posts, they are a wealth of info and experience.
