OK, so this is something I have never seem before in my pigeons. One female had an egg in the nest for a couple of days before I noticed. I had to throw it away as it was very dirty, covered in dried blood and poop. The female pigeon seemed ill, with droopy wings and lethargic. I thought she was egg bound, so I gave her treatment for that... trimmed her vent feathers, used warm water and steam to relax her vent muscles, gave her fluids and some drops of mineral oil in the vet to help the egg pass. But nothing happened. After a week she seemed to get better so I returned her to the loft. Now, about 10 days later, I go in the coop this morning to see she is standing over an egg. When I pick up the egg its got no shell.. its like a jelly egg, only having a membrane. It was disgusting... but it was clean and no blood on it. The bird seems OK. Do I need to worry? (I am always worrying about my birds). Is this due to a disease or diet or something wrong with her internally? She is about 1 year old and this is the first time she has attempted to nest and breed. In several years keeping pigeons and chickens I have never had this problem. The pigeons main diet is mixed grains and chicken LAYER pellets. They also have minerals and oyster shell grit. But maybe she is not eating the foods with calcium in them? Any advise very welcome. Thanks.
