No, the Sapphires are not auto sexing and from the few I glanced at this morning, they were either all roosters or the feather sexing also does not work on them.
It does appear that the Rose Comb Brown Leghorn/Cream Legbar crossed back to a Cream Legbar rooster have retained the legbar auto sexing trait. There are chicks with big clear white spots on their heads and their are those that are not.
You should have stopped by, at least you could have gotten a chick fix even if not actually getting any chicks. Of course there are the other things also. I am approximately 3 miles north of the Hat Six exit on I-25 on the east side of Casper.
I am still pulling chicks out of the hatcher this morning and transferring them to the brooder in the coop.
Sounds like you're going to have a busy day!
We're going to have to go back to Casper in the next week or so to get more stuff for the golf course, so if we can get up your way, I'll send you a pm. Love to see all those little chicks!
