So I have a really pointy one (white) and a really round one, (lower row blue) I will keep you up dated on this hatch.
All have been bred with a dark brahma mixed roo.
2 dark top row BCM/blue isbar (I don't know if they are fertile.), white is WCBP, 3 top right are from blue isbars, great big eggs for a small hen. bottom row I am pretty sure are fertile, 2 olives are from a blue frizzle, 2 tan are from a hen half blue isbar and half australorp, and the little round blue I believe is from an isbar/EE-isbar
