ok so i hatched out some eggs 1o days ago. got five chicks out of my five eggs sooo excited to have hatched them all. the egg came from my RIR hen so obviously they are RIR mix. I have two buff orpington and one black and white amerecauna. i thought the BO was daddy cause all the chicks looked just like him when they hatched and until yesterday when i noticed that they are getting little black spots on their wing feathers. could the amerecauna have finally got some action? or would RIR BO mixes have black dots on wings?
