They are cool.
My grandkids like to keep these eggs to the point that we have to get rid of them when they are not looking.
Great, now she tells me -- after selling me some Breese eggs.
JK- I "bought" that batch for the cochin and muscovies, the breese were just an add-on bonus, as anyone who's been the subject of wing's generosity knows she is prone to do. I do hope they hatch, worst case, I have a friend who likes raising meat birds, he will happily provide them a (temporary) home.
At least of of the dark skin and leg traits are sex-linked and I'm still trying to learn about that. I was not interested in silkie crosses until we talked, now I want to understand how the FM trait (that produces black skin and flesh) works. I've seen a lot of silkie crosses and they never worked the way I've recently heard that FM trait is supposed to work.
More research is need on my part before I can really say what you should do. There is a BYC user named nicalandia that I've learned a lot from. He's the one that described the silkie/leghorn cross, so if you ask him for advice it's a lot more trustworthy.
Drop those extra roos off at wingstone's farm, she'll give them a warm reception. Just don't mention to the kids what she will be doing to them.
I thought that broody silkie poop stunk. Today my broody turkey hen let out a load (almost on my foot) and oh boy that stunk up the outside air.
