and Welcome To BYC! X2 what drumstick diva said, with some breeds it is normal for the combs to flop over. If he is getting beat up you might want to introduce him more slowly so he doesn't get hurt. Introducing them through wire seem to work best, ie keeping the new one in a cage inside the coup for a couple of weeks. The chickens will get to know each other and sort of work out a pecking order before actually coming in contact with each other. There is a nice article in the Learning Center on integrating flocks you might like to check out, the part about actually combining them is after the quarantine section https://www.backyardchickens.com/a/adding-to-your-flock
