How long to produce babies?!?

[Apocha14]

I had a welsummer roo in with my true Ameraucana. I just recently moved him out and a true Ameraucana rooster in. That happened on the 17th. How long until their babies will be pure Ameraucana and not olive eggers?

I'd give it a month & then they should all be pure Ameraucana

Ok thank you! I'll do that to be safe
