We got 5 new 17 week old black stars last Wednesday. We kept them separate for 5 days. Our runs can be closed off from each other. At night we would collect the new chickens and put them in a dog kennel and then in the coop. For the most part all was peaceful except for the occasional scuffle. But now the new chickens are being forced into the coop and anytime they come out the old chickens chase them back in. I am hoping that this gets better soon, I feel so bad for the new birds and I was told not to inter fear with them, that they have to learn the pecking order. I am able to close the 5 reds we have in the other side of the coop when I get home from work and them get the new ones out into the run and they eat and drink. But as soon as I open up the door from the other run back into the coop they get chased. I hope they all start to get along soon. Any advice?
