I have a broody hen who is sitting on 4 eggs. She is in the coop with a piece of chicken wire around her nest box. It keeps her in, and the other chickens out, but I am not sure if it will keep in the chicks. I have had unprotected chicks killed by the other chickens before, and their own mother was mean to some foster chicks in the past. I am going to be gone for 3 days, at the same time the chicks are supposed to hatch. I am worried things will go wrong. I hope they are okay!
