My 9 month old RIR hen had a big hard white ball of poop stuck in her vent earlier this week. I got it removed, and brought her in the house so I could keep an eye on her. I made a post about it and didn't get any response. I have had her inside for two days now. She still doesn't seem to be feeling well. She has been eating some, but she hasn't drank any water. What might be wrong with her, and what can I do? I took a stool sample in to the vet and had it checked for worms and it came back negative.
