I have a six day old chick that keeps getting pasty butt. She's growing really great (she's the biggest one!), getting feathers,eating and drinking normally,and seems to act totally normal. I read that pasty butt if from diarrhea and then read that it's from constipation. Which one is it? I was thinking about giving her some coconut water for the electrolytes and maybe some plain yogurt. I am also going to try putting neosporin on her butt. Any other suggestions or thoughts about why this keeps happening?
