My 7 week old Speckled Sussex has had watery poop for the last three days. Occasionally there are small bits of normal poop in the liquid, but most of the time when I'm look at it come out it's clear liquid. No color. I have seen her drinking, but couldn't say if she is drinking any more then the other 4 chicks. She'd on an organic feed by Modesto Milling and has been for 1.5 weeks. I have been grinding up sunflower, pumpkin, flax, oatmeal + brewer's yeast whcih I give as a treat with fine grit sand from the bird store. A few days ago I added some regular bird gravel to the treat instead of the fine sand. Around that same time I gave them some meal worms. The watery poop seemed to start after that. She seems to be eating normally, is the first to rush over when I show up at the brooder. She's a very active little girl with a sweet personality. They are on pine shavings. Today is the first day I added a trace amount of ACV. I'd like to think this is normal, but none of the other chick's poops look like hers, and it's been going on for three days. I have looked at her butt, it's fine. I try to feel her crop, can't really say I know what I'm looking for, but when she stretches her neck towards me it looks very much like the other girls. Does anybody have any ideas what it might be or what I might give her? Thanks.
