So my broad breasted white turkey is sick again. 2 weeks ago i thought she had blackhead based one her behavior and poop. I treated her with fishzole and she got better. Today i noticed her sick again. She won't leave the coop and her poop has gone from nice and solid to almost liquid over night. I wonder if the safeguard I'm treating the flock with could have something to do with it. I put safeguard pour on in their water yesterday. 2 weeks aago i also put safeguard in their water and a few days later she got sick. Does anyone have any advice or suggestions?
