I have a small family goTs chickens ra bits. One day a black muscovy and white duck came into our yard they hang out with the chickens swim in a pool we have there and don't leave. So there part of the family. Picking up eggs on day I noticed eggs on the floor of the goat den in the corner covered with hay. In the afternoon I noticed the small black duck sitting on the eggs. I haven't touched them it's been about 14 days. The Temps are high 80s to 90s during the day and 70s at night. Do you think this eggs will hatch. The white duck is a male I've seen them mate so I am assuming the eggs are fertile. Should I just leave the alone and let nature take its course?
