I have 8 baby female chicks (from mypetchicken.com). They are about 3.5 weeks old. They all seemed fine and healthy until a few days ago. I noticed one that seemed a little less active and was every so slightly wobbly. Now today she is decidedly less active - mostly just sitting and often tipping over to the left. I have kept all 8 of them in a pen the basement the whole time, except for a few minutes when I tried to put them in a pen in the yard. They were able to get through the pen, so quickly collected them and put them back in the basement. I don't see any injury, no discharge, sneezing or wheezing. She is a little wet on the underside and a little bit of poopy butt, but not blocking the vent. I have seen her eat and drink, however her crop feels mostly empty. She is alert. Is there anything I can do for her? Thanks!
