that first male looks , or reminds me of what wheatons often color up like with that white in the breast, should all end up black though, if I'm not mistaken... havent had a chance to work with that color much yet. But that's what I'm thinking for now. If so he'll end up looking just like a bb red. You didnt hit columbian on him for sure though.
The middle guy, God who knows on that. It's not bb red for sure, it's not brown red. Kinda looks like a double laced of sorts. Brown red carrys a lacing to it, so it had to have come from them some where, but that will be one of those wait and see birds there.
That's the fun thing about these project eggs. You know what you should get, but that doesnt mean they'll all be what you expected.
On the last one. If it come from an egg marked SQ, it has to be a columbian. That's the only thing going in that pen, silver quail and possible columbian. I've had that pen of birds for about 10 years now and that's all that's ever come from them. Should get some black to her tail before long I would think, especially based off her chick down color.
