How Long Till Their Pure?

[Rainstorm]

I just Seperated my Welsh harlequins and magpies from the rest to have pures for springs. How long before I can assume the eggs are pure?

I would give it a month to be safe, though you can probably get away with 3 weeks and be pretty safe.

It is safest to give it a month to be sure!! Too many stories of cross-bred babies after separating birds into breeding pens for only three weeks. We need pictures when you have babies
