I had two muscovy ducks last year , they were given to me by a lady my mom had bought a goat from, well they didn't ever lay eggs. I gave em to a friend of mine that is making a pond for them. They had black wings and black on their back's half way down and orange feet but their bill was white like it had been scratched off . The bill by her face was like a green and mid way down it had faded so that it was white the rest of the way down . Does that mean that they were both too old to lay eggs?
