So I have a a button cage that holds my two single guys for sale a red breasted male and a blue face. Last week there was an egg in the cage just assumed that when I was moving everyone their had been a female in the cage. Well Saturday I cleaned the cages all freash and new. Today there where 2 eggs! Seems my blue face "male" red vent feathers and all is a female or a male with some major issues LOL
