So I had a dead hen yesterday, they are about 4.5 mos old, and after inspecting the coop and yard I found a few bloody/watery poops. I have started treating their water with sulmet and talked to a friend that said I should treat their food with decoccs as well. Any interaction I should worry about? I was told the only way to rid a flock of cocci was to treat very aggresively otherwise I could lose them all fairly quickly. Please help! Thanks in advance!
