I am just as curious! Since I also only have 1 pekin I was hoping that she would go broody. Though I also have 2 Indian Runners (1 a male), 1 Kaguya, and 1 Mallard drake. I am guessing it would be a tie between my Pekin and Kaguya. Since the third doesnt seem interested. From what I have learned you have to have your female with a willing male for 1 or 2 months first before you plan on trying to let her go broody. So you have a better chance at more fertilized eggs. If not and she had mated maybe once or twice, thats okay. It just means that you would have a probibility of 50/50 or lower to hatch. In a rare or normal occurance in the wild about 7/8th or somewhere along those lines. 2nd, lol oops. You need to know that pekins will sit on a certain amount of eggs and be prepaired to place a few fakes just in case. You'll know why in a second. (Been researching) Pekin ducks seems to like to sit on these number of eggs 7-10, 20, or even 30 or 40 eggs. Yeah I know thats a lot.... And youd be over run if not careful. Unless you want her to? ^-^' Well if you don't you can find fake ones in
walmart near easter or craft items, and at Hobby Lobby, or another craft store. It will take 25 or 28-32 days for duck eggs to hatch. Don't worry if the mom will go swiming then sit on the eggs where they get a bit damp. When or if she becomes broody.
She would like a dark and safe area to lay her eggs and make a nest. Sometimes its just to the side or in a corner. Since it had rained where I'm at I had to move her nest. -more like it flooded a bit- If she still tries to go to that same spot though, I would advise you to either fix the area up or make it a little different so you know they wont be sitting in a puddle. Once she makes up her mind she most likely wont change the area she chose. All we can do is make sure shes comphy.
Sadly you also can't rush a Pekin. Like putting all the eggs there and she goes broody at the drop of a hat. Yup won't work lol but my chickens would be estatic if that happened to them. Anyway... It just takes time. Let her go ahead and lay her eggs normally. 1 or 2 eggs every day till how ever many days she wants for the amount of eggs she prefers. If you keep taking an egg out just because you don't want her to lay that many, that gives you a higher chance of her ever going broody. (Hense where the fake eggs come into play) I have noticed that if I hover or stay close to my pekins nest, even when she is not done laying them all, she gets nervous or edgy. So I try to give her some space. Another thing, after a few days you will notice she will try to hide her eggs further by covering them up with twigs or grass or what ever nesting material she has. That means she might go broody! And I have also noticed that the female Pekin, if with a group of other farm ducks will try to guide all of them a little closer to her nest, and would chase my chickens away from her area if she didnt like them crowding over there for too long. My pekin, Annabeth takes turns checking the nest with Auburn, my kaguya. Well, thats as far as I've gotten. Its been 4 or 5 days that I have let them start for a nest. Don't worry if in the middle of the incubation time if one of your chickens actually scare off the mother duck and sit on the eggs instead. Apparently that had happened to someone and their hen hatched them all to the best of her abilities. I'd say they got duck egg envy.
You have to slowly add the fake eggs. Don't know if I have said that yet....
