I've got an Easero egg, but I can't make up my mind on what I want to do with it.

I can either hatch it, sell it, or give it to Phyllis for a basket.

Any opinions on what I should do with it?

I think you should hatch it and name it Steve. xD

No seriously, hatch it.

if you sell it you can get mre money for it. then its possible for it to be a rare color if you hatch it an it is natural the sell price goes down. it would also be nice to give it to one of your friends

Hatch first. Then sell. :) They're worth more.
