I'm fairly certain that my one silkie, Ellie Mae, has a defective shell gland. She is very healthy, but lays nothing but what I call jelly eggs (shell-less eggs). I've wondered if this may have something to do with the fact that she's never gone broody, whereas my other silkie of the same age stays broody. I don't sell my bantam girls eggs anyhow, keeping them for family and our use. No reason to cull her right?
