Oh, poor Gonzo.
Yep. I don’t know how to help him. I’m afraid to put him back in with Camilla because she’s too aggressive (he’s old and imperfect and that means the pecking order is in place, big time.)
The only other possibility is to get a young male to put in with Camilla and maybe a bigger flock will bring him out of his funk. Otherwise, I think he’s just going to die of misery over the death of Beaker.
