speaking from experience, which I know is not done often enough on forums, one male per 4-5 females is average for proven males. I do not have an ultra-sound machine so I have to rely on multiple copulations to make sure that there is enough viable sperm at time of ovulation. With young males, 1.5 yr olds and younger, 1-3 females is usually all that take and any more is wasting those females. Older males that breed with gusto and eat throughout the breeding season get up to 6-8 as long as I know the females that he's breeding cycle at different times (some females we have ovulate in december and some don't ovulate until april/may and they do this every year).
Now for the other question. Me personally I wouldn't get rid of any morph male until I can replace him with a homozygous animal of that trait or that trait plus homozygous for another, we don't have enough females for him to breed at least one, and all other breeder males are proven. You never know when a male just won't breed for you and having a back-up male, even if it is a pastel can make you a few hundred dollars or some females to hold back for future breeders. It makes no sense to me to pay price $X and then in a few years sell the same snake as a proven breeder for 1/8 the original price when you can just pick up a few females for a couple hundred dollars and make 3 times the money he would sell for the following season. The only males that I won't keep after getting a replacer male is recessive het males all het co-dom males can be utilized and the resulting normals can be sold in the newspaper or to local pet stores.
