(Resolved) My hen is lethargic, has white poop and is breathing heavily.

My smallest bird, Little Honey isn't doing well at all. She hasn't laid any eggs yet, and she barely has a comb or a wattle so I can't tell if she's about to lay or not. She usually has a lot of fun outside and comes to me when I call her, but today she stayed in the corner of the coop and acted very differently. I took her inside and separated her form the others. She's very lethargic, and is sleeping right now in my room in a cage with some food and water. Her poop is whitish yellow and runny. She's drinking normally but not eating very much. Shes always been significantly smaller and skinnier than the other birds, as well. I'm very worried about her, my birds are really important to me.

Update: (Its a little graphic, chicken poop/vomit warning.) My dad held her while I felt in her vent for an egg that could be stuck, and she puked clear and yellow liquid on my dad and when my hand left her vent it was covered in yellow white liquid with little bits of green poop. I didn't feel an egg from what I've read on BYC, but it was under my finger if it was an egg. I think the egg should be straight into her vent, right? Either way, I need help and we need it quick. I'm really worried about Lil Honey, and I'm scared we're going to lose her. If you can't answer, please send the link to this forum to anyone you think can.

 

Hey, thanks for the reply. She died yesterday morning.
I gave her a warm bath in epsom salts and it seemed to really relax her during her last few hours with me yesterday.
But thank you for telling me about feeling the crop and bringing up the reproductive disorders. That will help me do research in the future if any of my other girls get sick. Thank you for your time.
