I noticed one of my 2.5 yr old hens baby bad wings in the nest box for a long time with no egg to show for it on Wednesday. Then yesterday, I noticed she was drinking tons of water so I picked her up to look her over and she threw up all the water she had been drinking. Today, she was standing around looking tired and puffed up. And again she was drinking tons of water. When I picked her up being careful not to disturb her crop, she threw up so much water, I couldn't believe it. I brought her in and made her a special treat of eggs, yogurt and laying crumble and she wasn't at all interested in the treat. I don't know what is going on. Please help if you can. I don't know what to do.
