my chickens are 3 1/2 months old and seem like they have had coccidiosis for over a month. I tried sulmate, but that seemed to help for a little while and then it came back, so now i am trying corid, and have just started it today. do you have any more tips on how to keep it away. it seems like i can get it to go away and them in about a week it comes right back. I rake out their pen (which they are locked up in at night) nearly every day and try to keep everything as clean as possible. my mom wants to know it when they start to lay and they are not on corid or sulmate, and are free of coccidiosis if theie eggs will be ok to eat? and what if they still have coccidiosis? will the eggs be ok to eat? thank you so much!
