The one with the white on their tail looks like a Golden Comet. I can't say for sure tho but that is what it looks like to me. The other 2 reddish birds are probably what is called Production Reds. I am not for sure on those but I do think that is a possibility. And they are all wonderful layers...
This is Sunny (sunflower) and lays the blue/green eggs
This is TigerLily and lays the minty eggs
And this is Buttercup (She is a Lakershore Egger) and the one that lays olive eggs
Yes, chickens are VERY treat motivated! If they see me when I step out on the front porch, they all start running to the gate into their pen just in case I am going to bring them something. :gig
It is coming from one of your EE's. One of these 3:
I have one that will lay a light minty colored egg (is more green than blue), one that will lay a more blue than green colored egg and one that will lay an olive colored egg like yours. I just love all of the pretty colors!
