It should be noted that the UofA strain of Blue egg layers we have are not the same as what Whiting is now selling. Whiting's site states some of his chicks hatch with the chipmunk color pattern. None of the offspring from the UofA flock hatches with this pattern. They hatch with the standard blue/black/splash coloring.
So we will continue to call ours Arkansas Blues and to work on improving their color while keeping their egg production a priority.
We are seeing something unusual - mottling. We have a black hen that hatched from UofA eggs. When she molted last fall she came back in as a mottled. I am wondering if anyone else has seen this in their UofA Blues?
On another note.... the egg color is still a lovely shade of light blue and these are our best layers!
Did you have a different Rooster in with them in the last 30 days?
