Hi all! I recently got 8 week-old chicks (not a first-timer) and they all seem to be doing fine. However the smallest one has poop caked all over its butt and I am at my wits' end about trying to clean it off. I've managed to clean it to the point where there's no blockages to the vent but there's still a big lump caked on there, and if I try to pull it off she's quite obviously in pain. Does anyone have any quick fixes for softening the poop so I can clean it off? Thank you!!
