I have a white pekin female and 2 Swedish ducks male and female. My white pekin was born in march and started laying a few weeks ago. My male I have caught mating with my female Swedish but they were born mid April. Is he sexually mature? Also my pekin lays an egg each morning in the chicken coop floor since they all coop with my chickens. I do not have a nesting box and don't know really what I need for the ducks bc I wasn't expecting eggs so soon. Anyways she lays the eggs and I collect and then she goes back to the coop several times to check in there which she never did before. Is that a sign she wants to brood? Also since I haven't seen the male mate with her could her eggs still be fertilized? I did read on here that you can check by cracking an egg and I did that. It has a white spot in the middle of the yolk. then the second pic shows the white spiral stuff that keeps the yolk and white together. is my egg fertilized? I would love to hatch out some ducklings or let her sit on them but would just need to figure out what she needs.
