It sounds like an excellent decision to me.
With the Lemon Cuckoo Orp, you can just wait a bit longer and then make a final decision.
Go by your gut feeling, I have found that the best way.
I loved a SS cockerel that I got from straight run chicks.
Sadly I couldn't keep him, but he got though is teen years (or rather, teen weeks!) without the slightest hint of trouble.
I am in Australia though, so I guess the genetics could be quite different.
I don't think you should just go by...
