I guess 1 of my young 6 month old Muscovy duck female's have started laying I found an egg under my hay feeder and it is Sure not the chickens laying that big of an egg. But it is not as big as normal duck eggs will It get bigger as she lays or gets older. I have never seen a duck egg in person they are bigger then chicken eggs that is perfect I love chicken and duck eggs I am hoping to have around 50 birds. I have 30 birds right now. 22 chickens 8 Muscovy duck's. But which is funny my older drake Muscovy male has been wondering over to my neighbors to visit with her female he comes back over to my home but then leaves like 20 minutes later is there any way to keep him home other then penning him up I really hate penning birds up like I will have to if he doesn't stay home.
