I have two Muscovy ducks around a year old and this is the first time i have seen eggs. The problem is im not sure which one is laying eggs. I have one black with perfect feathers and a gray with not so great feathers both are close to the same size i can't tell them apart to sex them. The gray one doesn't move around like the black one lately and im not sure if the gray is laying eggs. i have read everything on the net with no luck. We now have three eggs but i never seen either one near the eggs. When I enter the pen the black one starts to ruffle its feathers and bob head around and the gray just sits in the corner and doesnt move just wags its tail sitting there. I'm worried i might have two females and only one is laying since its cold here in canada and im not sure if i should take the eggs away. Or i have a pair and I can't tell who is laying. Thanks in advance.
