We have three hens that have been pretty consistent on where they lay their eggs. We have converted a stall in the barn into a hen house. They are the only occupants of the barn. In their stall, there are a bunch of hay bales at different heights to give them multiple corners and different heights. There are also multiple roosting options. They have four nesting boxes, each has a golfball in it. One of the girls always lays in a nesting box - which one changes from day to day, but always in the box. The other two were laying in the same spot which is a nest area in the corner of their house. One lays first thing in the morning, the other late morning so they are not ever trying to lay at the same time. This week, the early morning girl has stopped laying in the corner and is laying in random locations. First, it was on the other side of the stall next to a door. The next day, it was on a hay bale behind a roosting bar. Today, in the middle of the floor. I just want to make sure this is not a symptom of a problem. Is this normal? Thank you.
