Hes upset but hes going to treat them so they wont get it.
Hes very upset about it tho. He said we have to who cares if he dies
(His immune system is down. He wont even take Tylenol when hes sick. He has to try to fight everything on his own cause of his lymes)
I'm very sorry your dealing with this.They might be mixed after winter but our winter will kill the parasite anyways.
You may want to do some more research on organic treatment for Coccidiosis in poultry. I just don't know enough about alternative treatments to make any suggestions.
It would be best if your boyfriend consulted his Doc about his concerns.
You mention winter will kill the parasite. Coccidia are protozoa, they live in the soil and in chicken poop (in the intestines), they may become dormant in the soil over winter, but cold weather does not kill them. Chickens naturally have Coccidia - this is why chicks in a brooder (even a cardboard box inside your house) can have an overload - warm, wet conditions and chicks consuming their own feces (all chick do this) - they can become overloaded without being outside on ground. It's only when there are too many that it overwhelms the system.
Corid (Amprolium) acts as a Thiamine (B1) blocker - essentially it starves out/prevents the Coccidia from being able to utilize B1 which it needs to grow/reproduce. This reduces the numbers and allows the chicks to build resistance.
