Uh hi!, I don't normally post here, but I went and found percentages for another forums. Found this thread while I was looking for another source to confirm the data I got from Bulbapedia about passing down abilities. Anyway here are the percectages(of you getting your desired pokemon. After you have all else done) for when you have a 6IV pokemon and 5IV pokemon holding the destiny knot and everstone.
The percentages of 12.5/25/50/75/87.5/100 are for the gender ratio.
If breeding a Hidden Ability.
12.5% = 0.7422% of the time or 1 out of every 134.7368 eggs!
25% = 1.4844% of the time or 1 out of every 67.3684 eggs!
50% = 2.9688% of the time or 1 out of every 33.6842 eggs!
75% = 4.4531% of the time or 1 out of every 22.4561 eggs!
87.5% = 5.1953% of the time or 1 out of every 19.2481 eggs!
100% = 5.9375% of the time or 1 out of every 16.8421 eggs!
If breeding for a normal ability when the pokemon species has two normal abilities.
12.5% = 0.9896% of the time or 1 out of every 101.0526 eggs!
25% = 1.9792% of the time or 1 out of every 50.5263 eggs!
50% = 3.9583% of the time or 1 out of every 25.2632 eggs!
75% = 5.9375% of the time or 1 out of every 16.8421 eggs!
87.5% = 6.9271% of the time or 1 out of every 14.4361 eggs!
100% = 7.9167% of the time or 1 out of every 12.6316 eggs!
If breeding for a normal ability when the pokemon species only has one normal ability.
12.5% = 1.2370% of the time or 1 out of every 80.8421 eggs!
25% = 2.4740% of the time or 1 out of every 40.4211 eggs!
50% = 4.9479% of the time or 1 out of every 20.2105 eggs!
75% = 7.4219% of the time or 1 out of every 13.4737 eggs!
87.5% = 8.6589% of the time or 1 out of every 11.5489 eggs!
100% = 9.8958% of the time or 1 out of every 10.1053 eggs!
Just note that you could get extremely unlucky hatch 100 eggs and still not get the pokemon you are looking for with the best percentage chance which is 9.8958%.
