I have a nice little flock consisting of about 150 chickens that range in age from a day old to a year old and I havent been fortunate not to loose anyone due to illness or disease (I've had a few random stupid things happen but not disease or illness)...until yesterday. I lost two teenagers. I thought it was from heat. But the next morning I had another die. This morning I lost two more and I put everyone in that coop in crates and was watching and noticed bloody poop. I seperated them into individual pens. Its cocci. I though it resulted only from a dirty coop. The only thing I can think of is that it started from wetting down the coops for heat (trying to cool them off). Hubby is going to get meds for them now. But considering the size of my flock, I want to have any medications I would possibly need on hand. Can any one give a list of recommendations for meds to have on hand?
