Hey folks, I have two Gold Star Hybrid Ducks from Murray McMurray that are supposed to be females. They are both about 6 months old and I have begun to collect eggs. I need some insight. One of the two has a much darker head, is a bit larger, and has mounted the other at least twice. Naturally I suspect that bird to be a male. However, I was getting eggs at the rate of one per night until the last two mornings I have found two. One of the eggs is smaller and thinly coated in some manner of light brown funk. I'm wondering if a) female ducks will attempt to mate with each other and b) do ducks commonly lay more than one egg per 24 hour period? Ultimately, I want to know if I have two hens or a drake/hen. I appreciate any insight. Thanks.
