I have a small backyard flock of 3 BOs hens (no rooster). I have two 5 week old BOs that I'm ready to put outside. Is it too soon? My plan is to put the chicks in my cat carrier at night in the coop. That way, they will be together, but they will be locked up. During the day I have the chicks in my garden, which is chicken wired. However, the neighborhood cat is getting interested and I'm scared it might kill them. Therefore, I would love to have the chicks in the coop with the other girls where I know they are safe. Is it too soon?
