I haven't seen any odd poop, and the other Orpington chick is also underweight, though it's as active as any other chick. It's just the one that's acting odd
I got 2 buff Orpington chicks at the beginning of the month (they're around 6-8 weeks old) and one of the doesn't seem to be doing well.
It spends most of its time sleeping, and hunched up like it's on a roost even though is not.
It also seems to be underweight. It's not sneezing, it's poop...
