Hello! My first batch of chicks are now 7 weeks old and getting rambunctious in their 2'x4'x2' indoor brooder box. We have five of the little darlings: a Rhode Island Red, Buff Brahma, Barred Rock, Gold Laced Wyandotte and Ameraucana. The hubby finally finished building our coop and run this past weekend and I am wondering whether it would be ok to move them out to their coop to give them a bit more room. The average weather has been in the mid-low 40s at night and in the low-mid 60s during the day. I know they would be fine during the day, I am just a little concerned about the temp drop at night. He installed a hook to mount their brooder light in the coop and there is an outdoor electrical outlet nearby, so we would be able to hang their heat lamp inside. I am pretty sure they have all their big-girl feathers as they no longer have any visible chick fluff. I have been doing a lot of reading on the subject and have seen mixed reviews, so I thought I would take advantage of the vast amount of chicken knowledge here ! Sorry if I seem like an over-worried chicken mom. It's truly amazing how quickly the little beasts can work their way into your heart and my two young daughters would be inconsolable if anything happened to "their cheep-cheeps". Thank you so much for your advice!
