So I merged the two Brahmas with my existing flock of 4 (all mixed breeds) and the babies are so afraid of the big girls that they won't even hang while free ranging in yard. Will get kinda close but run away asap. at night they fear for their lives going in the coop but, no blood has ever been drawn and are quite "chicken" in comparison to my other girls. They lay at the bottom of the coop to sleep...How do I get them to trust them and be a little tougher? frustrated!
