I have a 4-week-old chick that hatched under a broody in my chicken tractor. After it hatched, I moved mom and baby to a doghouse. Eventually I will need to move them back to the chicken tractor, and I'm wondering when would be the best time to do it. The hens have been able to see the baby behind hardware cloth all along. Now they are all free-ranging together and doing fine. After I move them, I'll need to keep them locked in for a while so they'll know where to roost, and I'm concerned about possible aggression toward the chick when they are confined. Would it be better to do it in the next couple of weeks while the mom will still protect the chick, or wait until it's bigger even though then it wont have mom looking out for it anymore?
