I have a 9 month old black star hen that has stopped laying and has been panting excessively (all the time). She has always been bigger looking than the other 3 black star hens and appears to have a swollen abdomen. But she's looked that way for the last couple of months. She also has had a swollen foot, but it seems to have been getting better without treatment. Other than hanging back and following the others around more slowly, she eats and acts just fine. Could she be egg-bound? Internal laying? A bacterial infection? If she is egg-bound or an internal layer, should I put her out of her misery? Any help is appreciated. Thanks.
