We have seven chickens, all about 5 1/2 months old, bought the week they hatched. This is our first time with chickens. Bahoud, a Jersey Bronze, started laying a few weeks ago and all was good at first. We have lights on a timer and she is on layer feed. A little over a week ago she laid an egg with a soft shell, relatively solid but I could dent it easily with my finger. The next day she laid an egg with a very soft shell. I added some oyster shells to their feed. We went away for a couple days and the neighbors collected the eggs, so I am not sure what, if anything, she laid while we were gone. She hadn't been laying for a few days when we got back and this past Saturday I noticed she was hunched over and the entire back end of her body was sort of pulsing, moving up and down. I brought her inside in a tub and she was not eating, drinking it pooping. I looked through forums on this site and found lots of advice. We gave her warm epsom salt baths and I did put my finger in her vent, but don't know what it supposed to feel like, but I didn't feel any eggs. Something came out if her in one of her baths (maybe unformed shell?) and some poop came out when I had my finger in her vent. She laid an egg with no shell Monday morning and .I took her work with me in a tub so I could keep an eye on her. She has been eating, drinking and pooping, but she is still hunched and pulsing, although the pulsing isn't as bad as it was. The poop is green and small. She also feels lighter than the other chickens. Does this sound like she is egg bound or something else? Is there anything else we can do for her?
