So this may seem like a strange question, but how and when does a duck decide to go broody? From the best of my knowledge i am gathering that she is a mallard mix, she is mallard color, with white tips to her wings, and white ring around her neck. She was with males before i adopted her, and has so far laid over 8 eggs, my question is will she eventually want to brood? I have read that some ducks go broody with somwhere near 20 eggs, will she need that many? I can easily get more eggs if i need to. Any suggestioins or info would be greatly appreciated.
