I have 4 hens, none who are laying eggs yet. I have a red sex-link, 2 buff orpingtons, and a silver-laced wyandotte. The 2 buffs and the red sex-link get along fine in the coop and are close in age, the SLW is like half the size of the others (around 10 weeks old). I introduced the SLW to the 2 buff orpingtons and they all get along fine, but the red sex-link is so so mean to the newbie SLW. She keeps viciously attacking and pecking the SLW, not drawing any blood because I don't give her the chance to. So the SLW has been in a homemade brooder in my garage at night and in a small wire pen inside the chicken run during the day. I thought that the red sex-link would get used to the SLW that way but I tried introducing them again this morning and the same thing happened. The SLW is almost outgrowing the brooder and idk what to do. Someone told me to try putting the SLW in the coop with the others at night and when they wake up they won't even realize that the newbie was ever different from their already established flock. But I am hesitant on trying that because I don't want to wake up to a dead SLW. Any advice from someone who has dealt with this before?
