It depends where you go and how "red " the red really is in the parents and how much of red is showing through the hatchies I have seen them anywhere from $70 to $110 per hatchling
I've just paid $100ea but in the past i've been lucky to get them for between $50 and $80. It all depends on how strong the colouring is with the parents pretty much and of course what your willing to pay.
