Hello, I have this Black Star (laying) hen that eats freshly laid eggs if she is in the coop. My mom suggested blowing out the whites and yolk out of a egg, and filling it with mustard to see if the next time my Black Star eats it, she won't like it. Me and my dad were doing this craft that involved poking a hole through a egg, and blowing out the whites and the yolk, but blowing was to hard. So my dad sucked the whites and yolk and ate them. It would be hard to do it again, so I don't want to put him in any trouble. Any better ideas? Thanks!!
