Nope.

you should be fine. adding another roo would likely cause some fighting and barebacks.

but every situation can be different, so just keep an eye on everyone, and check eggs for fertility (if that's what you're going for) and adjust accordingly.

how do you check eggs?

 

[MetalSmitten]

you have to crack them open and look. a fertile egg will show a subtle, white-ish "bulls-eye" type mark, a small circle less than 1cm in diameter. it can show up anywhere on the yolk.

once you've checked fertility for a few days and are happy that all/most eggs are fertile, you can start saving them for incubation if you want.
