One dozen fertile hatching eggs. The hens are RIR, Ameraucana, Barred Rock, and White Leghorn. The roosters are RIR, Ameraucana, red sexlink. I put 40 of these eggs in my incubator and 39 developed! ( 37 hatched!) I will also add extras for free. All the chickens free range together (except that ameraucana) therefore I can not guarantee that the chicks hatched will be pure breeds. The ameraucana are in a separate area so those eggs are pure. I can guarantee they will be fresh, fertile, and great layers! My chickens are free range and very happy! If you have ANY questions feel free to contact me. I prefer Paypal. Thanks for looking!
