So I started seeing blood in the brooder yesterday and I thought perhaps someone was getting picked on...after closer inspection this morning I see it is blood in the poop. So Cocci right? Now can I treat them with the sulmet even though they are on medicated starter. They range in age from 2 days to one week in the brooder. I believe the dosage is 1/4 tablespoon per quart. Is it safe to medicate them at this age? Any advice is really appreciated!
