Well here's how we're doing a double homozygous:

We're shooting for Super pastel Hypos (granted, not double recessive, but still double homozygous).

We went ahead and purchased:
1) pastel hypo male
2) pastel het hypo female

This will improve our odds per egg (compared to a potential breeding of double hets) from 1/16 to 1/8. If we don't hit the super pastel hypo, we'll keep back a nice female if we get one, and keep trying.

By using a homozygous hypo male, we're guaranteed that any pastel or super pastel females we keep back will be at least het hypo, and will be worth pairing up in a few years to have more chances at the combo...if we have bad luck and don't hit it by then.
