I guess I'll start from the beginning... In May, my roo (only roo I had at the time-yes I'm positive!) died. I gathered eggs for the next few days and incubated 6 eggs. The hens I had at that time were only 3 breeds: Partridge Rocks, Dominique's, and rose comb Brown Leghorns. I got 2 chicks from each breed. Link to the thread here. it was my firs hatch, so i had to tell the world. . Here is a link to that thread. https://www.backyardchickens.com/t/...s-gl-brown-leghorndottes-and-wyandiques-oh-my Here are the only photos of the rooster, Rocky, that I have. He was given to us at 5 months old. I was told he is a hatchery stock GLW. Here he is a week or so before he died. Here is when we first got him. It shows his breast lacing. Here he is with his girls. The first black sex link from the Dom x GLW laid a green egg. I know, because I stalked the coop for several days and watched. The first green egg threw me for. Loop, so I watched after 2 more eggs. I figured at that point, that either her mother or father had the blue egg gene somewhere. Today, the PR x GLW laid her first egg (hooray!). It's green. Here is the pr cross hen and her egg. It's quite an olive color, which can be hard to tell from the lighting in the photo. The speckles fade when the egg is dry. Her egg is in the middle, between a barnevelder egg and an EE egg. Yes, I'm sure this is her egg. Was Rocky an Easter Egger? He doesn't look like a cross to me, but he was the only Wyandotte I owned. If he was the offspring of a Wyandotte and some other blue egg gene carrying bird, what could it be? Wouldn't Ameraucana or EE genes have shown through somehow? Like messy lacing or different colored hackle/saddle feathers? Now that he has two daughters from different mothers who lay green eggs, it has to be him, but I can't figure out the combo here. Do two different brown egg layers produce an olive egger? Never heard of that before, and I don't think it's possible. But I could be wrong? Or is there something else I'm missing? I've done a lot of reading but I'm far from an expert. Thanks!
