February 24th I went to my coop to collect eggs from my hens and I found one of my girls walking around hunched and not activity running around for the treats I tossed. Took her home believing shes eggbound. I felt her underside and it felt normal I didn’t really feel anything hard or super squishy gave her 2 epsom salt baths, after the first bath she looked way better then later that night i gave her tums, put oil on her vent  and gave her the other bath. Not sure if it was after the first bath or second but when drying her she pooped just water and I didn’t think much of it. I gave her a dark area to stay and provided water and food, she did eat a bit but didn’t seem super interested and she was drinking quite a lot of water I checked her crop before night and it felt normal and hoped she would pass an egg by morning. The next morning I found nothing but her still hunched over I felt her crop and it emptied like normal so I didn't think much of it, As I take her out to clean up the area she stayed in she takes a huge green and white watery poo and that made me believe she was sick and perhaps not eggbound. I then made her some scrambled egg and she nearly ate it all and was still drinking lots of water. I let her be for a while then returned cleaned up where she was because it got dirty and tried giving her a bit of yogurt and crumble to help with the diarrhea. She didn’t seem too interested in the food but she did give a few pecks here and there. She was still drinking more water than food. Around this point I noticed her making an almost gagging like reaction but it wasn’t a lot and I thought she could be possibly adjusting her crop and didn’t think much about it Later I returned and seen that her poop was actually starting to get shape again but it was still a bit wet I thought it was looking a bit better and left again. Returned tonight to find her hunched over again, beak open, and making the gagging reaction again aswell as her poop being complete diarrhea again. I gave her an epsom salt bath to try and relax her and I think it worked. During her bath she had her beak open and almost breathing heavier than she usually does. After her bath I noticed her underside looks swollen, I felt it and its not rock solid but its not squishy either it is stiff but has squish but I’m not sure if its because shes got diarrhea or other reasons. I replaced bedding in box and placed her back inside. I’m so stumped I don’t know what I’m dealing with. I’m super sorry for the long read I really don’t know how to shorten it. Please if you have any information that can help me I will be grateful
