I have a hen that has been broody for a week. I got some fertile eggs I put under her this morning. She got out of the nesting box to eat and another got in to lay an egg. She just went to a different box. I put her back in. This is her favorite nesting box. Later I go put there and she is in a different box so we put her back again. She is still there now and definitely broody. The question is why is she changing boxes and what should I do to make sure she is in the right one? I have been going out there and collecting eggs often.
