Hi, so I have 4 baby chicks I had shipped to me last week. They are one week old today. All arrived fine, then a day or so later my partridge cochin bantam male, snoop, developed pasty butt, I washed his butt off, and then he seemed to get a prolapse vent, I still washed his butt off, gave him sugar water, apple cider vinegar water, scrambled eggs, hardboiled egg yolk. Today, the other chicks started to pick on him so now he is in his own box. And today he can barely stand his eyes are closed mostly and he cries alot. Every now and then his eyes open and it's like he's trying to live. Is there anything else I can do?
