So I have had my two original birds (hen and roo) for 7 months which I kept from a total of 6 birds (I had 5 roos). A little over a month ago I got a new girl and since I'm new at this I didn't separate her. I just let her in the coop which didn't go well, she ended up with an injured eye. Could be pink eye or a pecking injury. I put her in her own pen while caring for her. I then got two 8 week old RIR pullets which are in their own pen in the larger run about two weeks ago. How long should I wait before opening that pen and letting the two original birds mingle with the new ones? I have seen one of the originals chase and bully the one with the eye injury so I'm a little worried. Will the quarantined one ever be accepted into the flock?
