I'm going to try an experiment this time around. They say that pullets hatch from the more rounded end eggs and cockerels from the more pointy ones.
Them I'm going to do the pin thing over them also. Round and round pullets back and forth cockerel. Double check them you see.
I trying to see if this works, so far this year is seems I've been coming out with about 3/4 cockerels to a 1/4 pullet ratio.
Let me know how that turns out for you!
Amazingly I am hoping for a roo in this hatch. I have shipped off all my boys so I currently have a girls club. I did that in anticipation of a good hatch with 50% or more boys (as is my usual luck). Watch them all be girls this time. That is just Murphy's Law for hatching.
I miss the crowing. :-(
I'll try to remember to come back and tell how it turns out. I'll have to wait a few weeks to be able to tell for sure what the sex really is.
I know the feeling of wanting which ever. This past hatch I was hoping for a cockerel myself from my 1/2 Black Jersey Giant NN hen. I got two offspring but they are both looking like pullets.
