I have an ISA brown chick about 6 weeks old. I got her with 4 others. The others are growing and are starting to feather out but she is still the size of a new chick. She is starting to get wing feathers. I wouldn't necessarily be worried but she seems to sleep alot, but does have awake times where she will walk over and pick at the food and I also have seen her at the water can. She is starting to get a "distended" belly where it feels fluidy and soft. and when she walks she is starting to waddle more I think because its hard to walk. I do see some poop marks on her back side so she must be pooping at least a little (but I feel like she hasn't been going enough?) She is not "pasted" up like i know some of them can get and I checked her vent and it doesn't seem to be blocked. Can they get blocked farther up in the digestive tract? I haven't really been able to find any info on that. Any suggestions I can try to get her to poop more?
