Once you get the PokeRadar from the shop (after saving up 150,000
Pokedollars for it), you can chain eggs of the same species to
increase the chances you'll get a shiny. Though keep in mind in
PokeHeroes, having 2 different species breeding means the egg will
contain either species and not just the female's species. Using the
Wide Lens will let you know what the eggs contain so you don't have
to worry about breaking a chain.
Make sure to train my bird!
