This will be my 4th layer in a week! WooHoo! BUT I don't know who laid it! That's where you experts come in! I have an 18 week old Black Sex-Link and an 18 week old Black Australorp. Only the BSL has been doing the squat but the BA has been more friendly as of the last few days! My next youngest ones are in EE at 16 weeks and 2 Welsummers at 15 weeks, so I know it's NOT those 3 and I have seen all the others lay so it HAS to be the BSL or BA......so who lays a lighter brown speckled egg???? The coloring doesn't do it justice, and the speckles are all over the egg. And silly chick pecked a hole in the egg! I can see the indented shell and it didn't puncture the membrane cause nothing is coming out!
