I'm brand new from NC but have raised chickens most of my life. We moved to a different house 9 month ago and don't have chickens right now BUT I need advice about a missing female Mallard. She laid a couple eggs around my pond 2 weeks ago, but has now disappeared! I walked all the way around the pond a few days ago and found the remains of about six eggs, but they were all empty and demolished, as if maybe a coyote??? We have had a gradual influx of coyotes in our area over the last 10 years. The male mallard continues to hang around, as if looking for his mate! It's really sad. I don't know if she was attacking killed or throw away. The male continues to swim on the pond, but he's very lonely. Can someone with more experience in mallards tell me what could have happened, or what I can do? I put out canned corn about every other day, and before she disappeared the Mallards seemed very happy. I'd appreciate any advice at all! Thanks in advance
