I have always wanted to hatch some duck eggs but that means I have to buy a bator And I dont want to buy that if my ducks will do that there selves. I have 4 rouens 1 female 3 males and one ancona female and one khaki male and a pair of call ducks, the calls are three months old, and the others are five. and the five month olds just started breeding. Does that mean they will lay eggs then? I also have 4 welsh harlequins and and two rouen females on the way As you can see I need more ladies. But what im trying to do is sell ducklings to my local feed stores for some money, will my ducks hatch enough babys to make it worth my while? Or should I save some money for a incubator? Help me!!!
