Hi. I brought 4 chicks home today, and one of them has hard clumped poo on it's bottom. I tried pulling it off, but its really stuck, and I was afraid of hurting her. I tried wiping it with a damp cloth, but it just won't come off. She's a really sweet chick, I don't want her to get sick, how can I get this off? Is it ok to give it a snip? Thanks.
