Another white Leghorn has a messy vent crop is full of water and she is still drinking. She seems off balance also. Having trouble walking on the roost. Her poop is clear and slimy looking. I felt to see if she was swollen in the abdomen but I don't feel anything. Could an egg have broke inside her? I'm searching the internet for some kind of solution. Yesterday her qsister was culled due to large mass internal laying. I need help
