The problem with silkies though is that they have vaulted skull's under all of that fluff, and if that soft spot is pecked by a bigger breed, it can do some real damage. Silkies aren't the only breed's that love to go broody. I had some hen's earlier this year that went broody and one of those went broody twice. I didn't let them hatch though, so I broke them of it. I prefer to hatch in my incubators.
I have a couple of Lakeshore Egger pullet's that should start laying in another month. They hatched from green egg's.
