I have a barred rock hen who isn't doing so well. I caught her and separated her from my others because her crop is SO full, it's bulging and she's separating herself from the others. I noticed it today. It's not hard, it feels like there is liquid in there. I read to smell at their beaks to see if you smell a sour smell and was afraid to get my face that close. She isn't happy with me. I did notice though an odd smell when I was near her, hard to explain the smell. Not sure what's wrong but any advice would be appreciated! I wanna get my gal better and she wants with her pals!!
