As I was staring impatiently at my broody bantam silkie this afternoon, (she is on day 20.) I noticed her neck/chest was spasming out every now and then. I though that maybe a chick was hatching, but it became apparent something was wrong with the hen. I felt her chest and noticed she had a very hard crop. (About the size of a golf ball.) She has been a very die hard broody and barely gets off the nest, so I put a little dish of water in the nesting box with her, which she started drinking right away. That was at 4:30ish. I juay went to check on her again, and she has drank quite a bit of water, and her crop is now squishy. Do you think it's sour or impacted crop? I wouldn't think so because she has barely been eating regular food, let alone something that could cause blockage. But something is wrong....any ideas? She is acting normally otherwise, e.g. Not hesitating to look at me indiginantly and peck and growl at me. Really hoping and praying she and the eggs will make it!
