My guess would be that the two darker chicks are little cockerels that inherited the auto sexing gene from your roo. And the white chick is a pullet that the white gene from the hen dominated the legbar colors. The white spots on the top of the heads of the darker chicks is a normal indication of a cockerel when breeding true legbars. Typically the pullets will look similar to those dark chicks with more defined chipmunk stripes but no white spot on the head. I think that if you keep breeding that roo with that hen you will always get white pullets, anyone feel free to correct me if I'm wrong, I'm learning some about the genetics but far from being an expert. LolSorry if this is a duplicate from the cream legbar thread but was advised that I might get answers here. I have a trio of CL's, the pullets are yet to be laying, but the young cockerel has been in with a mixed flock. I allowed one of my hens to sit on three white eggs (only have one male, and one leghorn so I know who is who when laying). The three eggs hatched today, so I am happy with fertility on this young lad . One was definitely yellow based and the other two were darker. Pictures are posted. Can someone explain the difference in these chicks? And no, there are no other males in the mixed flock. I haven't seen the two young pullet CL's in the nest boxes. I only set the three white leghorn eggs, I thought the leghorn/CL mix would make for good egg layers for next year. Here are pics of the leghorn female and the CL rooster. The female was supposed to be a SBEL, but looks more to me like a leghorn, she lays pure white eggs. She has faint splotches on her that are either bluish or grays in color. (and just to reiterate, the three chicks here have the same male and female pairing. No other roos in the pen). I am just amazed at the color differences.
