One of my ladies is acting like she is trying to lay an egg but there seems to be nothing there. No hard lump or anything. But she is pushing. She is out of sorts, not eating much and doesn't want to move around. We thought she was egg bound so we tried the warm bath, put her in a warm dark place, used lube and did an internal exam but unless there's an an egg way up inside her we can't feel anything. She is pooping, but its all white. Any ideas? hate to see her like this... Oh and she is a 1 1/2 year old buff orpington that has been a great layer in the past.
