Yes. I'd rank the nursery upgrades as one of the best uses for gems.

Basically with only 1 nest if you get a dragon with a long incubation time (IE. Crystal/Forge with 24hrs) then you are stuck waiting that full time before whatever your breeding can be put into incubation. With 2 nests you can just keep breeding and incubating.

3 and 4 nests are less important but if you get the Epic Breeding Island then you'll definitely want them and if you upgrade both the island and cave for the faster breeding times then you'll find that even with 4 sometimes you'll get backed up.
