weird behavior

[mvasquez63]

I have a 22 week australop chicken that started act strange she lives in a chicken coop with 6 other austrolops and 7 rhode island
chickens. She has always been roaming around by herself but also she has been eating along with the others. Now suddenly she has
separated herself from the other and she has started to act strangely but first let me say tell you. the chicken coop is quite large and it has plenty of space for them to roam around the coop is 16x16 and the other part is 40x40 so when she is by herself she all alone
with non of the other chickens around and she just lay there on the ground suddenly she jumps around for about 3 to 5 seconds like if another an animal was after her then she lays down very tired unable to move I can even pick her up without any problem. I've seen her do that several times and she is not eating or drinking water I had to force her to drink water with a dropper let me said that when she is rested she is very energetic and I have a hard time getting her.
please tell me what is wrong.

Welcome to BYC. Before you said that she wasn't eating, I thought that she might be dust bathing in the dirt or shavings. Is she laying eggs yet? How does her poop look? Could she be egg bound? Feel her crop, check her for lice and mites.

It sounds like she is living in great space. We need to know more about her, though. Age? Is she laying? Has she been laying recently? What is she eating? Any other birds sick? Is her belly swollen compared to the other birds?
