We mixed the Corid on Wed. Thur. poo looked ok, But this morning Fri. when I scooped from under the roost one was dark [old blood] brown with slight red and one with what I think was intestinal lining, it was a little bloody. The rooster is still pooing golden foamie stinky poo / At 3p.m. I went out to rake up poo in the run and found another dark poo. ???? Do you think the dark poo is normal???? All the hens are molting and haven't laid eggs for a month .
