My Sebastopol gosling hatched 3 days ago and was active and healthy at first. Today I noticed her backside is very wet and messy looking. She seems to have diarrhea as I’ve held her in a towel for an hour or two at a time and she is only making wet spots. She appears to occasionally strain, squeak, and wiggle her tail as if trying to poop but produces nothing but watery drips. I’ve put electrolytes in her water and tried to keep her quiet today (away from parents) since she’s having trouble keeping up. She is mostly sleeping and seems wobbly in her feet. She eats chicken starter feed, has access to grass, and I’ve shredded her fresh parsley. Any advice?
