Thank you for the info Dancelife. The GoldEggs I asked about, were the 3 prizes (assuming no treaty) you get at the end of every 3star RR.
The 5 GoldEggs you mentioned is a daily prize for finishing 1, 3 & 5 3star RRs.
What I'd asked about should be, in theory, unlimited. I am not aware if there is a limit to the number of RR a player can do per day. Don't know if those throw out occasional GoldEggs - that is what I was trying to verify.
