Hi- I have 2 chickens that seem to be depressed. they are staying in the coop all day. I am not even sure if they leave to get food and water. They are in their nesting boxes. They aren't laying any eggs but sitting in the boxes as if they did. Not sure what I should do. Should I force them out of the box or just leave them be? This has been going on for about a month now. thanks in advance!
