I have a Sapphire Blue hen almost a year old, who recently went through an episode - I found her in the coop kinda closing her eyes standing still, just not moving around and pecking much. That night she didn't get up on the roost with the rest. I brought her inside and inspected her.. it seemed like she had sour crop but it would be a first for me so I'm not really sure.. her crop was squishy and warm in the morning so I did some of the online suggestions but never made her throw up, withheld food for a day, gave her acv, probiotics, greek plain yogurt, watered down food etc. and after after a few days she seemed fine. She had some runny poo in the beginning, but in the end of her isolation poo seemed pretty normal albeit not a lot as she didn't seem to be eating a normal amount. She's been in the coop almost a week since that happened, and her activity level seems pretty normal like the rest of the hens (perches, pecks around) but today I noticed she has runny gold colored foamy poo. About a month prior to finding her not feeling good, I'd noticed that for weeks someone had this runny gold colored poo but I could never figure out which hen. Back then I did a 5 day treatment of Corid in the water and it seemed to clear up after that, but then it came back about a week or two later. Could this one hen still have Cocci? is it a sour crop problem or something else? I thought Cocci mainly effected younger hens... I've also had 3 or 4 slightly wrinkled eggs which I'd never had before and one rubber egg in the last month or so.
