I just got 7 new baby chicks...I put them in our tub, made sure the temp was right, put down some pee pads with pine shavings on top, made sure they all ate and drank and then started to check them for "pasting up" I've never owned chickens before so I'm not positive but it seems like they are pasted up in the front and not the back?! Unless thats something else from when they were born? like a chicken umbilical stump...lol?? I'm lost! It seems like their little butts are clear but the front is crusted over?....not sure if I have it backwards and should try to wipe it off or if it's something I should leave alone.
