can you move the nest box to the corner, let her lay there and get used to the box and then try moving the box back to where you want it?
Just an idea.

This will be an interesting thread because we have four Barred Rocks that will be laying in a few weeks. The older hens are shunning them and won't let them get near the nest boxes. They were introduced to the (free range) flock about a month ago and haven't really been accepted. They always just hang out together.

I'm afraid we are going to have the same problem as you because they hang out in the woods a lot.

Something else you may want to try is to put a couple of fake eggs in the nest you want them to use. I bought wooden eggs at the flea market, painted them to match the brown hen eggs. They helped quite a bit.

My first experiance with moving hens was they laid their eggs on the tool holder. Which meant the eggs fell through the holes. So I put a cardboard box on the shelf part.

They liked that idea, and laid in the cardboard box. So when I moved the box, they looked for it. Then I put the box where I wanted them to lay, and shut them in for a week. Bingo!

Great ideas here...

In addition to providing really cool, dark, hidey-hole type nests elsewhere, if you have straw or other type of litter in the corner they are laying it, take it away. You can also try placing a large, hard object in their fav corner such as a rock so ther is no longer a spot to lay eggs. It doesn't have to be forever, just until they get the idea of where eggs really go.

Thanks all, we did move the nest box(es) to the floor and she is using it. When we move it back we will block the corner to keep her out of it. Got two girls laying now :-) Big Star has layed now 13 out of 15 days with two dbl yolkers! We read they were supposed to miss days when they first start but she must not have read that book! Not for sure who the second layer is, she snuk(sneeked) her first in on us just today.
