We have a 4 chickens to 2 nest box ratio. One would think that was plenty, right? They all want the one the other is in. They will pace back and forth and fret when it's occupied, sometimes climbing in with the other or ousting the other and today this exchange happened over and over. Every time I looked they switched. The crazy thing it's not always the same box, today the left box was the favored one, but tomorrow it could be the right one. They crack me up.
