I have a 14 month old Wheaten Ameraucana hen that started laying at about 12 months old. I waited and waited and waited for that blue egg, and then she started laying a white rubbery egg! I tried giving her extra calcium, but its been another month and still no improvement. She also has one gimpy, curled up foot. I'm wondering if there's something genetically wrong with her that caused both the curled up foot and the soft shells? To make it worse, someone (maybe her) has been eating the egg after she lays it - I just find yellow goo in the next box when I go to collect now. Anything else I can try to improve the shell of her egg?
