I've never had any problems with my chickens in 2 years (other than a coon got one). Well, I've got a problem now: For about 2 days my wife has noticed one of our Delaware hens has been missing feathers on her back end. I didn't think anything of it since this has happened to all my chickens at different times of the year and they all turn out okay. I wend out to put them to bed and noticed a broken egg. I looked closer and the shell was like jelly (see pic below). I then noticed the chicken's back end had yellow on it (egg) and was quite a bit bigger than her sister (second picture). I then zoomed out with my flashlight and noticed egg juice all over the place (last picture). Is this an eggbound chicken? I'll be honest that I'm not one for taking a chicken to the vet, but I also don't want it to suffer. Other than the obvious, it seems healthy (which is why we didn't notice anything). Any suggestions would be great.
