Ok so I have about 30 ducks, mostly male, and haven't had time to separate most of the males from the females. All but one are welsh harlequin the only other one is a pekin. The pekin has always been good at laying her egg in the same spot unhidden. Well the males are at the point were they wanna breed, and I've seen them breed with mostly, of course, the pekin. Now she's hiding not only her eggs but two of the other ducks started laying and she's hiding them to. So here's my questions. We were out of town for three days, the guy who was going to feed/water/ collect eggs couldn't find anything, we come home and oh, Harley has them of course, do you think they are developed enough to incubate? It's been about a month or two of them breeding before they started laying again this year. Question #2 another egg I candled from last week, I was bored and home alone, looked like it was fertile. How long can an egg sit out (not in fridge) and still be able to incubate? Last question, I'm building an incubator, what temps/ humidity should I keep it at? And when can I tell if they are developing? Thanks in advance!
