Chicken & Guinea hen mating

[chicknbutt]

I currently own one male guinea hen who has became the "pack leader" of my flock of chickens. Recently I noticed the male guinea hen has started mating with the hens. Around the same time my hens have stopped laying in the coop and all have been laying in a nest they share in some brush. One of my hens also started to go broody and has decided to lay on the nest 24/7. Is it a possibility the guinea hen and chicken eggs are fertile? The breed of chicken I caught the guinea hen mating with are buff orpingtons and the broody hen laying on the nest is an Easter Egger.

Guinea fowl/chicken hybrids do occur. Some of the eggs may be fertile.
