I originally posted thinking cocci as one of my 4 girls was pooping blood. Today would be day #4 to treat for cocci. I had read somewhere In these forums about a similar situation. To treat cocci first and then deworm with safeguard just in case. On day #3 of cocci treatment I gave safeguard orally. Now they are pooping a ton of round worms...... I used my chicken health for dummies book to identify them as round worms. Should I finish day 4 and day 5 of Corid? I am thinking of doing 5 straight days of Safeguard vice the other method (1x then repeat 10 days later). Is that a safe bet? What else should I be doing to help them? When should I give them the multivitamin to replace the thiamin the Corid took away? When should I give probiotics? Could I give them some treats like cabbage? Because it's a back yard flock, in a suburban setting, I am not able to move the coop around nor change yard. I have sprayed the coop with a bleach solution and a pesticide since day 1. I am planning to do this daily for the next two weeks to kill everything. But honestly.... It the issue of the ground.... What do I need to do with my yard to prevent this from happening again? Help!!!
