Several days of mild to hot, intensely humid weather....................now past fishy smelling diarrhea, some definite blood in it. no poops are fully normal; once in a while there is a loose normalish looking one fed some DE, mix of poulin layer and egg production plus feed he is alone no other birds of the 22 seem affected--all poops seem within normal range......... he eats and drinks and is active all day, eagerly pacing along the fence, wanting to get back to the rest of the flock. he has almost STOPPED vocalizing. he usually makes some various normal noises............ feathers below vent show the whitish wet smear of the diarrhea--sometimes it comes out like a little 'jet'. I AM RELUCTANT TO TRY A COCCI-STAT SINCE I DON'T KNOW WHAT IT IS. 16.99 for Corid in a bottle (liquid) i guess. (Does this stuff work?) vet is not an option he seems a bit too old for cocci. this bird is NOT listless at all, at all, at all. just slightly bloody poops, and strange silence.......... ?
