So far this is what I have..... Batch number 1 resulted in 11 live chicks from randomly selected eggs. At this stage there are 5 definite males and 5 definite females. 1 I am not sure.
The second and third batches were also from randomly selected eggs but resulted in only 13 live chicks due to clumsy broodies squashing the popped eggs. It is a bit early to tell yet for sure but I think there are 7 males and 6 females.
The fourth, fifth and sixth batches have resulted in 27 live chicks and are too young to sex. They range from only 10 to 1 day old. All of these chicks are from rounded eggs that I selected by eye not from measurements.
I have a further 23 eggs due to hatch anytime all are selected eggs so I will keep you posted.
