One of my roosters has not been himself lately. He is eating and drinking slowly but just sort of slowly ambles around all puffed up and disheveled looking. I've been keeping an eye on him and notices he has been having foamy yellow poops. I tried to look up the cause and treatment for what could be the problem and came up with a few things. I've seen that it could be a sign of coccidiosis, but another page also said that coccidiosis always presents with bloody poops which his are not. And blackhead is another possibility, though coccidiosis and blackhead have two different treatments. I've seen that it could be worms, though I have not seen any worms in the poop, so I am not sure what kind if there are any so I am not sure how to go foward and treat him. Anyone have any ideas or input? No one else in the flock seems sick, they are all eating and drinking. The rooster in question is a couple months over a year old.
