In anticipation of spring, when I've heard male ducks can become... overly amorous, I have several questions on what I should do. Right now I have: 3 female welsh harlequins 2 male welsh harlequins 5 female runners 5 male runners plus 2 female geese (african & toulouse) What do I need to know about breeding ducks? I'm assuming that if I want purebred offspring, then I should separate the welsh harlequins and runners. Not 100% sure how I'll go about that, since they all share 1 big house right now. Is my male:female ratio ok for the welsh harlequins, or should I only have 1 of the boys with the girls? I know I have too many male runners, but hopefully 3 or 4 will be finding new homes come spring. What triggers an increase in breeding behavior? More daylight or warmer weather? Hoping its warmer weather, since its still VERY cold here (gonna be 5F tomorrow night!). Do ducks breed year round or are they seasonal? How do I find out if duck eggs are fertile or not? How do I choose an incubator (assuming I should go this route since I've heard ducks generally aren't broody)? What do ducks need (as far as housing, nesting, feed, etc) to breed?
