Well my Orust all have strong veins. My other eggs are just dark enough not to be able to make out things clearly with my regular lightbulb. Hence why I ordered one of those super flashlights. I still haven't fessed up to having the rares in the incubator. I sold an Olive Egger roo with two hens to make room for new chicks. My DH is holding my math at 12. So I am going to have to fess up soon. I was hoping to finish the new coop and run before doing so. He is always on to me about jumping in at a run and putting the cart before the horse. And he is not totally wrong .......but I had a chance to get the rare eggs for $49 on an auction on Ebay. One of those Orust chicks are going fro $99 unsexed at Greenfire. To me it is worth the gamble and hard work it will entail to hatch them keep one of the breeds and sell the others or keep two of the breeds and sell my Olive Eggers. If he is going to hold me to 12 then they may as well be 12 rare chickens that I can make more money with.
