I have 5 baby chicks that i got 3 weeks ago and i raised them inside and i take them outside now every day and bring them back inside when it gets dark (May be too cold for them) but the problem is, is that when i take the chicks outside my adult chickens (2 hens 1 rooster) are mean to them, they peck and BITE them a lot so i always separate them (Chicken wire) however how long will this last? or how can i stop it
