I have three Muscovy hens on nests. I have one Pekin drake and one muscovy drake. I never dreamed when I got a pair of Pekins that the drake would be so aggressive! He pesters my muscovy hens to death every time he sees them and breeds them a lot. the muscovy is not nearly as aggressive nor persistent. My question is, reckon what percentage of the eggs will be hybrids and when will I be able to tell the difference? Both of the drakes are white.
