Hello. One of my girls has had a bit of a dirty bum but has seemed herself otherwise. Yesterday she didn’t seem her self and away from the others and hunched. She isn’t eating or drinking much but still is. I have checked for mites and worms but can see any signs of this. For now I have put her inside her own setting....is this the right thing to do? Will she be ok in there on her own? Do I need a make shift nest box? (she has never perched before - ex batt so haven’t made a perch) Any ideas on what else I should check for or what it could be? many Thanks I have attached a few piccies.
