I have 3 pekins, have no idea about their sex( I have never seen any mating behavior). They are about 10 months old, and to my knowledge have not laid any eggs, until yesterday, maybe. They have always free-ranged so it is possible they have laid elsewhere. I have 30+ chickens that have free-ranged with them most of their lives. About 6 weeks ago the chickens got a new run and I have not been letting them out much because of the poor weather. Anyway the ducks have shelter and two "nest boxes" in with my 7 nigerian goats. Yesterday after letting my chickens out for the afternoon, I went to gather eggs and decided to check in the goat shed (I had given up on the ducks laying, assuming that I had three boys), I found 1 very dirty egg, on the ground, it was a bit larger that a normal chicken egg, but not larger than a few I have had in the past. I had no idea how old it was so I cracked it when I got in and it had a very large yolk, probably twice as large a a normal chicken yolk. So I thought maybe it is a duck egg. So i went back out tonight to gather eggs, I decided to check the goat shed and I could see where it looked like someone had been in the nest box, but I could not see any eggs, I decided to rummage around in the box a little and found a dozen eggs like the one from last night. DO DUCKS BURY THER EGGS? Or are these old eggs from when my chickens were free-ranging 6 weeks ago???? I know some of you will say why hasn't he cleaned out this nest box in 6 weeks, well it is just half of a litter box in the floor of my goat shed and I had given up on the ducks laying so it has jsut been sitting there as far a I was concerned. Any thoughts would be appreciated. Thanks.
