Crazy question... My wife saw a call duck today, and now wants some!! We currently have 3 female Khaki Cambells. I have located a pair of Snowy Call Ducks for sale, 1 male, 1 female. Being that our Khaki's are for egg production (and my wife is a vegetarian!!) I really wouldnt want the male to be attempting to mate with the Khaki's. will this happen? or due to the size differences, etc. will he not be likely to try?
