Crocheting my little heart out today to finish a blanket for a baby born last week. I've never had 12 chicks at once before and they stink! Sour smelling. At least one has thick, foamy poop. I have probiotics in the water; maybe the feed isn't good? I had a couple with droppings stuck on their bottoms, but only one I'll have to soak. It doesn't look like the pasty butt I've seen, but it doesn't seem like it could be anything else.
