Thought I'd join in the fun! I do not battle competitively, so I DO *NOT* IV breed.
That being said, this doesn't mean my Shiny hatches can't be disappointments anyway LOL!
Female Shiny Dedenne, yes but CHEEK POUCH I wanted Pickup...Grrrr...
MALE Shiny Pachirisu with Run Away--Also wanted Pickup... Boo...
Here we go, let's start by pledging 500 eggs (I'm there or over, Seviper in-progress...)
MM WITH Shiny Charm, results as follows, BOTH parents are the same species unless otherwise noted. Same-species parents also SEEMS to allow for a higher Shiny rate, but again, data, data, data LOL!
Dedenne: JP ♀, ENG ♂: 380 Eggs/1 Shiny
Pachirisu: JP ♂, ENG ♀: 180 Eggs/1 Shiny
Seviper: JP ♀ Seviper, Local (American) ♂ Zangoose: In-progress...No shiny yet BUT that completes the 500-egg run, still going so let's pledge 700 in total.
