I have a Scovy 'mule' drake, Panda, fm a surprise hatching last summer. I had planned on keeping him since he was such a cutie and figuring he wouldn't be adding to Scovy gene pool wouldn't cause to much of a problem. He does 'breed' the Scovy hen's every chance he gets and DH tells me that could lead to fewer fertile eggs being laid... and subsequently fewer ducklings hatching out. I've thought what he's told me thru.... read some articles on mules and sterility & hate to admit but I do believe he has a case. What are your thought on this? I would hate to loose too many potential ducklings by allowing him to breed the girls.... and he is good at it..... quicker/faster runner and lighter weight than the Scovy drakes. Here's a pic. Tks!!!
