please help, our barred rock has been acting strange for the the past few weeks, she’s been keeping her head very close to her body and not like the other barred rocks, we’re new to chicken keeping and she’s about 26 weeks old, the reason I’m only just asking is because now she is on the edge of our dust bath(terraced) and sort of squatting and bouncing slightly upside down, she’s letting me touch her(not usal) and they were all just squawking and clucking and screeching very loudly(not egg song) she and her 2 sibling barred rocks and 1 other different chicken have not laid yet, though 2 other chickens have been laying for a while now. Please help. I’m worried she’s really sick.
