I have a lot of jolly aerodactyls, just hatched one with 6 perfect IVs and will trade the others:

>5 perfect IVs
31/31/31/31/31/x x3
31/31/x/31/31/31 x2
x/31/31/31/31/31
31/x/31/31/31/31

>4 perfect IVs
31/31/31/x/31/x
31/x/31/x/31/31
31/31/x/31/31/x
31/x/31/31/x/31

Want:
some other pokémon with 4-5 perfect IVs or just offer shinies.

Also how should I build it, 252atk/252spe/4hp?
