It's not uncommon for young birds to have an overload of Coccidia (Coccidiosis). Coccidia is a protozoa found in soil and in poop. Warm wet conditions the oocysts can flourish, so it would be really hard to say if it was due to the chicken sitters' actions.Yes thank you I found the dosage and am giving her medicated water and trying to do the drench .
all the others are getting the medicated water as well. The poop looks exactly like the examples on the web. As far as balanced diet they have a good feed from our co op plus the scratch is only a small handful a day . Then a handful of the dried meal worms from rural king and then usually a fruit or veg treat like blue berries or cucumber or watermelon. All I can figure it it’s because we were gone and things were done properly as far as how they got it ?
You are giving fruits and veggies - is grit provided as well?
I would focus on the chicks eating chick starter for most of their diet, limit the treats.
