I have two situations I would ask for anyone's help on. The two ladies I am going to talk about are both about a year old. The first one is a brown leghorn. My son (the owner of the ladies) let them out of their coop last Friday morning a little after sunrise to forage in the back yard. About 9, he noticed "Foggy" standing in the corner of the yard with her head and tail all drooped down. We watched her closely and she seemed to be going down hill rapidly. About 10 we decided to soak her in some warm water to she if she was egg bound. After we soaked her she seemed to pick up a bit. But, shortly started back down hill. We soaked her agin to see if that might help and I felt of her abdomen to see if I could feel an egg, which I could not. At about 2, we decided to take her to the vet, he gave her a shot of antibiotics, Unfortunately, she died a short time later, while we were driving back home. Anybody have any ideas on what would make a seemingly healthy bird go down hill so fast? Should we be doing anything for the existing birds as for as watching or treating them for anything. Then this morning, when he went to let the three remaining hens out of their coop he found that his Easter egger had laid an unshelled egg. Shortly after, she "laid" or passed a membrane or something that was 2 & 1/2 to 3 inches long, tapering from about 1/2 in to 1/8 inch in diameter. The small end was closed and the large end was open. I have watched her today, she has eaten and drank well all day. She has forged on green grass in the backyard this afternoon. We keep oyster shells out for them at all times. Does anyone have any ideas on what might be wrong with this chicken and possible treatments? Should we isolate her from the other two hens?
