Come this weekend, my goal is to get our 6 standard size (5 and 6 week old) chicks moved out to the coop. We have 5 bantams that will be going into a separate coop shortly after. I'm new to raising chickens and can't help but feel a little worried to officially leave them outside all night. Our temperatures recently decided to drop as well, and we cannot run electricity to the coop for heat. They have quickly out grown their brooder and we have already upgraded the size of the brooder once. At night the temps are usually low 50's could sometimes drop to mid 40's. I guess my question is, are they going to be alright outside in the coop all night without heat? How low of temps can a chick that age handle? We don't have the room to upgrade their brooder again and they're quickly getting sick of each other as they out grow their space. Our weather is usually quite sunny and beautiful. Of course the passed 2 weeks when we've been trying to finish the coop and get the chicks moved out, it's gotten cold and rainy. Any advice on the transition from brooder to coop would be greatly appreciated!
