this a long time in coming...4-9 months! anyways, as you know little Jumper is a crested mallard, and SHOULD be a hen, if she is when she ia old enough to breed, and takes an interest in my non-crested drake Jacobi. what will the ratio of ducklings be in terms of crests and not?? I was always told crested x non = 50/50 chance for both, basically if 10 ducklings hatch, 5 will be crested and 5 will not? is that true??
