I followed the Addon Example to create my custom dragon breed and replicated the folder structure. The only thing I edited was the biome_tag, the blocks to surround it, and the texture for the dragon & egg. I tried testing this in the game but it doesn't work and I'm not sure why. What I mean by "it doesn't work" is that when I try to hatch an egg to test it the only thing that spawns is the regular Ender dragon or I get the green particles for the green(nature?) dragon.

I would appreciate the help! thanks in advance.
