I've had issues with cocci in my flock for months. They can go a month acting fine then after a rainy spell or when I add a new bird the new bird will suffer and die. I've been off and on treating the water five days or more in a row then skipping five and retreating. But I think I have such an infestation I need something more long term. Would a medicated feed be suitable to add along too? Do they medicate layer feed that I can buy at my TSC? I feel bad because I am in the works to start breeding seramas but any buyer will have a big footnote to their purchase: treat this bird for cocci before adding to your flock!!! And this morning a pheasant was really wobbly and weak. It always seems to make them weak and lethargic and then they lay down and pass on eventually. When I take stools in to be looked at the ones who end up passing or seem sick are always heavily infested. All I can say is ARGH.
