Olive Egger + RIR?

[TheAlarmCluck]

I have 2 chicks that are a mix of an olive egger rooster and an RIR hen. Is there a specific breed for this mix?
If not, how can I tell if it will lay green or brown eggs?
Thanks!
(If you're wondering, the chicks look exactly like Rhode Island Reds.)

This is a good thread to read.... What color legs do the chicks have? https://www.backyardchickens.com/threads/rhode-island-red-easter-egger-cross.402645/page-3
