My four Faverolles chicks came yesterday and since then, there is one runt in the otherwise hyperactive bunch. She sleeps a great deal, drinks water and HURRAH - saw her poop a little while ago. But otherwise all she does is peck weakly and am not sure I've seen her drink. I've sort of held back from messing with her as I don't want to add to her stress. Any ideas? I can't bear thinking she may just be on her way out.
