I have lost 7 of my 30 cornish cross rocks to coccidiosis with in the past 2 days. I treated with sulmet today. I did not know they had it. the first hatchery I bout the first 5 from had did a spray vaccination on them and I did not know it and fed them medicated starter for the first 2 weeks well they turned 2 weeks friday and sunday we had 3 die today I had 4 to die. If any of them make it will we still be able to eat them if not we are just going to cull all of them and count it as a loss. any imput would help greatly thanks.
