I have a 2 1/2 week old Partridge Silkie that has had nothing but problems since I got her. She is MUCH smaller than all the other chicks, although she eats and drinks just fine, and the other chicks don't peck on her at all. She also is a lot more timid than the others. She has had a LOT of pasting up, but I've been very diligent about cleaning it off several times a day. The past couple of days she has had mucusy looking stuff around her vent. Then just now I saw her looking like she was straining to poop and her whole vent area poofed out to like the size of a marble (keep in mind this is a really tiny chick). It just bulged out weirdly while she strained. Later I saw her poop normally though. Please help. She is such a sweetie and I don't want to lose her.
