It's always best to keep to the same thread on one chicken. That way all the info is in one place. It saves precious time, ours and time your chicken needs to get help. If no one has answered your thread, try pinging some of us here that you might have noticed are popping up on threads helping people. That gets our attention quicker than anything.
If that fails, add another comment to your thread to bump it up to the top of the list. If your chicken is sick and needs urgent help, you are entitled to be a pest.
@Ursuline Chick mentioned the wide stance that might indicate liver failure or ascites. You would notice that chicken standing with her legs far apart, inches farther than normal with swollen abdomen in front of her legs. That would tell us she might have tumors that are shutting down her organs.
If you hen has a swollen bulge behind her legs just under her vent lends more weight to a reproductive infection. The "orange ball" pictured in the poop photo you posted is likely lash material or chicken pus. It usually indicates a reproductive infection. These can kill quickly or slowly. Sometimes a hen will live with it and behave nearly normally for months. But in the end, there isn't much that can be done about it.
Your hen's behavior tells me she's feeling very sick. If you have any antibiotics on hand, you can try giving it to her. But do check her crop as it can indicate that you need to treat for a blockage. The pus can block her, causing the crop not to empty. If that is the case, we can treat that and make her more comfortable in the short term.
