New to chicken keeping, we got our first set of chicks. All of them seemed to be getting along well until 2 weeks ago (they were 4 weeks at the time) when 2 of them were bleeding from their backs pretty bad. I separated the injured ones and treated them and let them heal. Once they healed I have been trying to introduce them back in. Every-time I do the others attack the lighter one which I am assuming is a rooster. they are now 6 weeks and I tried again and the others jumped on top of him pecking him like crazy and he was screeching. I separated them. Is this a lost cause? Should I rehome him with the one he is bonded to now? I’m so sad because they are SO sweet and I love them so much but I don’t want to risk their life and I hate seeing them so scared with the others.

Do they have adequate space?
