I have a muscovy hen which is about 1 yr old. She hatched off one brood earlier in the year. Now she has built a nest. I have observed her plucking feathers and everything and she even sits on it some during the day. However, she hasn't laid a single egg in it. This has been going on for 2 or 3 weeks. I have never had a bird that was not laying start trying to set. Has anyone else seen this? I have considered that something may be getting her eggs. However, that seems unlikely because I am collecting eggs every day from the pen from the other birds with no sign of an egg eater. I have also checked the nest immediately after she got off of it several times. She seems to get around fine, although I have wondered if she could be egg bound or something. Does anyone have any ideas??
