The other day, one of my younger hens (this is her first year laying eggs) started laying on eggs in the weeds on the side of the road down from my house. I thought for sure I was going to have to shoo her off and then incubate or toss the eggs so she wouldn't get eaten in the middle of the night by a predator. However, I was able to remedy the problem and thought I'd share since I used this same type of plan with success a few time last year with a different hen. Here is what I did:
I took a large Rubbermaid container and cut a hole in one end and put straw in it, then quickly shooed her off the nest and tossed her eggs in the container. I then placed the container exactly where I had found her nest and covered it with weeds and surrounding vegetation. She came back and continued to lay on the eggs inside of the container. When it gets dark each night (since they are practically blind at night) I sneak up to her and cover the hole in the container with a big towel and carry her back to a dark coop where she sits on them all night. The next morning, she comes out and I carry the container back to the spot she initially layed them. She follows at a distance, then goes in and lays on them. I just repeat this process every day. It's a bit of work, but to me, it's better than having to incubate the eggs myself then worry about integrating new keets to the flock. Just thought I'd share in case anyone else has a similar problem...I know Guineas are famous for nesting where they are not supposed to!
