Some of my chickens (2 years old) have watery diarrhea. I took a few samples to the vet, samples were from the roost in a couple places and then from the ground where one pooped as I was watching. I gathered up what I could, but the sample wasn’t great. Took it all in, vet found nothing. They haven’t been wormed, so I’m going to do that. But my question is-he wanted to treat with antibiotics, thinking maybe the diarrhea is from a bacterial infection? However, he advised tossing eggs for 2 months. Can I use Tylan to treat this instead of the one he’s wanting to use?
