One of my hens appears to be broody. We were out of town for a few days, and when we got home yesterday she was sitting in her nest, and, so far as I know, hasn't got up since (though I assume she is getting food and water, I haven't seen her do so). My neighbour who cares for the animals when we are away collected an egg from Beatrix on Monday, so this behavior is very new. I'm inclined to let her continue, just to see if she takes it to its conclusion. However, this hasn't happened before in my little flock so I would appreciate advice. How does this usually progress? And when do I start counting the days? Thanks.
