1. How many eggs to choose from for this incubation? 11
2. How many eggs set based on "female profile"? 8 (3 were from a hen that lays rounded eggs only)
3. How many eggs survived to day 18? 4
4. How many chicks hatched? 3
5. Percentage of pullets in this hatch? 1 pullet, 2...
my experience:
NN eggs, mostly pointy and I got girls from less pointy eggs.
BCM eggs, all round, she has never laid any pointy egg, I got 2 boys and 2 girls.
my conclusion: if all the eggs has always the same shape sexing eggs is impossible. if the same hen lays different shape of eggs...
are those eggs round or pointy? my NNs lay pointy eggs but some of them are a bit less pointy. my bcm lays round eggs. I think they have always been exactly the same shape. I put 3 (under a hen) + 4 (under a muscovie duck) of her eggs and wait to see if they hatch.
I will be following this thread. I will hatch with the broodies only so I will have less eggs to incubate. I chose less pointy eggs in december and as only 2 hatched I don't know what the others would have been. but these 2 are pullets
