Breeding Colours Questions

[BirdNerd101]

What happens if you breed:
1. Blue Swedish X Blue Runner
2. Cayuga X Black Runner

And if you want purebreds, how long do you have to seperate the colors bedore you can start collecing eggs?
Thanks

For saftey / to just be sure for pure bred, i woud wait 2 weeks before you start.

and for both of those breeding pair\s you get a mix of the two they could look different everytime.
