The male may not be able to breed this up coming season, you might be able to get the female to size by March with a 10-15% or 15-20% feeding schedule, but she may not want to breed.
If it's the 11-12 breeding season you want them sized up for a simple 10-15% feeding schedule upgrading weekly would easily get them there.
I really want them for 10 - 11 season.
Would a good 2 feedings a week do it ? But bigger meals ?
