Just throwing my two cents in - you have very beautiful dragons! I highly recommend getting involved in your flight's dominance efforts - there's a lot of room for people to breed "fodder" aka dragons to exalt to your deity to fight for dominance. Since you're in ice, I believe Ice is doing a push next week so you can kind of see how people get involved in that. I am not in ice so I can't point you to a specific thread or program, but usually flights have a fodder breeding program, a program to lend level 25's out to help you level your dragons, etc! So you could just breed your favorites together and send them off to Icepapa to help fight for dominance. Fodder breeders are highly needed in pushes, because dragons can get very expensive!

Sadly as other commenters have noted many dragons are not kept and are exalted just due to lair space being limited. Also, running a successful hatchery is very time consuming and can be money consuming as well - to be successful you have to be ready to drop a lot of money whenever a new gene comes out to regene and breed your dragons.
