How long did you let it rest before frying it?
I have found the resting time is more important than the breed. I also have found I like the taste better on an older bird than the 6-8 week old CXs.
I let it rest 48 hours in the fridge, before I bagged it and froze it. I don't know if it counts as additional rest time, but it spent another 2 days defrosting in the fridge.
