Amm... we HAVE a limit freezing hatchlings, but i can't remember the exact limit...
If you don't want a Egg, you can abandon it. For the CB eggs, I already gave an idea: can't freeze before the 5 hours wait.
Lucky you to see 10 different breeds in the AP, I usually see 3 or 4 (Pinks, Peebles, Frills and Mints most )
(I'm going to be one of those freezing pink eggs )
You have a good point with the codes... but think that giving them a different code could mess with the lineage system... maybe >>
Besides, I don't like the "back together" idea, what if I only want 2 Splits and an egg? Should I raise "x" number of dragons to get the egg, and then kill/release the remaining adults?
And, if I'm releasing them, they are counting in the ratios, and they are not exactly commons... 10 pinks for every Split I send to the wilderness... that's worse
