I got my first flock last year and I swear they're bulletproof! A fact I took for granted until this year, when I got more chicks and chickens and... Very ominous music, please: dum-dum-dum I've lost half the chicks/chickens I've gotten this year to coccidiosis. My hope in starting this thread is to have a place where we can come for advice and support in the prevention and treatment of the dreaded Cocci Parasite!!! Any other parasite prevention and treatment is welcome, but this is primarily for Cocci help/support.
