So I had a good hatch! Bonnie and Clyde are two Pilgim's born 4/29/2013 and they came from Metzer farms.
My intention was to keep one girl and sell the rest, so I put an ad in Crais
Gas list and got four replies.
One wanted 2girls and a boy. Check

e
One wanted two girls (and requested they stay with mom until pickup) check.

One wanted one boy one girl. Check

The last wanted fertile eggs, no go. Next year? Yes.
Bonnie had a total of 10 under her, and one was under a chicken. So 11 were being "cooked".
The one under the chicken I thought was too old anyway, and that one looked like scrambled eggs inside.
Of the other 10 under Bonnie, all of them hatched, and only one died, it was fully formed but I think it got squashed while trying to hatch, because it's abdomen didn't look fully cooked. I pulled it out of he nest and tossed it a ways away.....and we held three girls outside for a bit, trying to avoid Clyde's beak. Bonnie just watched us, and stayed close. After about 15 minutes all three were on the ground with me showing them the. Water puddle I made since they can't hop into the baby pool yet. Mama saw this and started to drink a bit from the puddle too, very cute.
Then, she really surprised me. She waddled over to when I had tossed the dead one, and examined it. How she knew I can't guess. They both examined it, then left. It was sad.
So we had a 90% turn out for goslings! with only two males! which is what I wanted!
Turns out I will have two geese plus mom and dad....and my Sebbies.
