I am 98% sure my hen has cocci (have dealt with it a few times before). I got a fecal test at the vet and they said they couldn't find anything. She has bloody poo though so I have been putting Corrid in their water (2 tsp per gallon) but it doesn't seem to be helping and she's getting worse. In the past I have always had to resort to Sulfadmethoxine powder because the Corrid never seems to clear it up completely (this is why I was hoping to get some Sulfa powder from the vet). They don't want to give me any but I have some from a few years ago and I am going to use it out of desperation. I believe it is 1 tsp per gallon. My question is, if my hen is still alive tomorrow, how can I get her to drink the water? Can I put powder in a an empty pill capsule and give it to her that way? How much would I give??
