I have 2 BRs and 4 EEs that are three weeks old and growing like crazy. I have already expanded their brooder to give them more room, but the seem like they need more room to run around. The coop is all ready to go but there is no electric and I can't get a cord out there. Temps here are getting warmer it is high 60s low 70s in the day, but still getting down in the high 30s at night. When can these girls get out into the big girl coop? Will they be ok to be out there in the day and come in at night? How old do they need to be to be out there full time?
