I had a blue cochin rooster, this is him hiding in the corner from a blue wyandotte who was not coming to beat him up but to see is he was going to do rooster duties.
Below is the same hen walking away frustrated. Look at her face!
I had a very sad Welsummer with a bad wing. Since she could not roost I gave her an at the time 4 week old chick, I bought from someone who didn't want a rooster. He is now about 9+weeks old. The have bonded ever since and he never leaves her side and her wing seams to have healed.
