1 Champagne male can go to many females and will be ready to breed sooner.
Where as is you buy a female your going to have to wait 2,3 or maybe 4 years until she is ready to breed and even then your only going to gonna get one clutch with the gene.
Its just you get a quicker turn around, the reason basic/cheaper morph females are more expensive is because they are considerd bases for more expensive genetic combos.
