I have an unusual problem! I found a brooding hen (not mine) in my backyard! She's chosen a corner under the trees where two fences meet and has been sitting on 14 eggs for about 2 weeks now. Last week I candled a few and think they are fertilized. It's been cold and raining and raining so I chanced making a little lean-to roof for her to keep the rain off, but it's cold and damp and I'd really like to move her into a shelter but I'm afraid to move the nest in case she doesn't come back to it. What should I do?
