Faith is a 22 week old Seckled Sussex pullett. I noticed that she has seemed listless and not interested in treats over the last week and I saw her "heaving" like she was trying to throw up. Today she was up in the coop and I was petting her and noticed that her crop was huge and felt like it was full of liquid. I picked her up and gently held her by her feet and supported her crop area and there was a lot of whitish thick liquid that came out of her mouth, well over 6 oz of it. I lifted her up regularly to let her rest and she didn't seem too stressed. When no more liquid came out, I put her down and petted her some more. There is still a mass of stuff in her crop and I can feel something like sand. Anyone know what is wrong with her and what I can do? She's a real sweetie.
