Hi guys,
I'd like to contribute my findings on here. I got the shiny charm a few weeks back and have been breeding poochyena's. I'm doing batches of 330 due to having 11 boxes empty. Batch 1 and 2 both had 2 mightyena's. Male was german.
Batch 1 - no shiny
Batch 2 - 2 shinies. This 1 had an extra egg and the extra egg just so happened to be shiny :)
Batch 3 - 1 shiny
Batch 4 - 3 shinies
Batch 5 - In Progress
1,321 eggs hatched so far.
Eggs #381, #661, #875, #1081, #1242 and #1262 were shiny
In Batch 4 I switched to a 6iv Spanish ditto for the last 2 n a half boxes. Batch 5 I will keep the Spanish ditto and use a froaki I will breed
