I have a chicken that just sits under the coop all day and refuses to eat. I'm a little worried. She is on antibiotics for severe bumblefoot and I'm wondering if the antibiotics are making her feel sick. I have given her Greek yogurt before but I'm wondering if it's possible to give her a little bit of the activia flavored yogurt for her digestive track? Would that be alright? Also, she hasn't laid an egg for 18+ days, and I'm concerned about egg binding. I don't know if I should mention this, but her poop is green..... not sure if that tells you anything, but I might as well throw that out there!
