These are eggs from our pure breed chickens but the chicks could be either pure or mixed as they all run together. The hens are RIR, Americauna, Olive Egger, White Rock, Cornish, Black Cukoo Maran, Buff Orpington and Silver Laced Wyandotte. There are two roosters, one is RIR and the other is Buff Orpington. These are young layers and roosters and very fertile. I pick up the eggs while they are still warm and will send them out within 3 days of collecting so you get the best chance of hatching all the eggs out.
