Speckled Sussex

[FrozenChicken]

My neighbour wants some eggs for thier incubator off my speckled sussex hens so I separated them with a Speckled Sussex rooster but the hens were amung all the other roosters all winter. So my question is how long before I can get 100% for sure pure speckled sussex chicks?

I've heard sperm cannot be retained past two weeks, but I would wait three weeks just in case.

I have read on here that 3 weeks would be a good time to waite. Then you can be sure they are pure!
