Five weeks ago I aquired some pekin/rouen mixes and the plan had been to let them forage about my yard. But I began to wonder could my cats take on the ducks and would they? I was hoping that some of you might have info on the matter as I look into what type of enclosure to build the little creatures. Also another quick question on sexing them, since they are crossbreeds can I assume that the ones with the greenish black feathers on there heads will be drakes or is that lost in the fact that they are mutts? Thanks so much.
