Ok, here is a little help. At level 5 it is difficult to tell it's DVs.All Skarmory born at level 5 will have the following as their stats:

Hit Points: 21-23

Attack: 13-14

Defense: 19-20

Speed: 12-13

Special Attack: 9-10

Special Defense: 12-13

To be sure what your DVs are, you can use rare candies to level it up to level 50 (yes it can be a pain but it's worth it)

Anyway, make sure that you do not let Skarmory win any battles or the DV Rare Candy trick may become flawed.

All Skarmory rare candied to level 50 from birth will have the following as their stats:

Hit Points: 125-140

Attack: 85-100

Defense: 145-160

Speed: 75-90

Special Attack: 45-60

Special Defense: 75-90

Now, at level 50, you can find it's DVs by doing this.

To find it's Hit Points DV take 125 minus whatever Hit Points your Skarmory has. The number you get is it's DV (ignore the negative sign you get if any)

To find it's Attack DV take 85 minus whatever Attack your Skarmory has. The number you get is it's DV (ignore the negative sign you get if any)

To find it's Defense DV take 145 minus whatever Defense your Skarmory has. The number you get is it's DV (ignore the negative sign you get if any)

To find it's Speed DV take 75 minus whatever Speed your Skarmory has. The number you get is it's DV (ignore the negative sign you get if any)

To find it's Special DV take 75 minus whatever Special Defense your Skarmory has. The number you get is it's DV (ignore the negative sign you get if any)
