I found out that my chicks are dieing of coccidiosis, I can't get to the feedstore tell Saturday which stinks but I can't. What would be the best meds for them. I have to about 35-40 birds, including chicks. Plus cheaper would be better, but I guess I dont care if my chickens lifes are on the line... please help. Oh and once I treat them do I have to wash the coop, or will it be ok?
