Ok, DH is bugging me to ask something. We have a blue kiddie pool near our pole barn that is filled with water and decaying leaves and has duckweed and watercress floating in it. Every morning when the chickens are let out, they all flock to this pool and drink from it before doing anything else. They have water in the coop with them so they are not suffering from lack of water, but this is what they do first thing. They drink from it all day long so we refill it if it gets low, but DH wants to know if anyone knows why they are so attracted to the pool and its water. A simple 'because they want to' from me isn't cutting it with him. So, is there some possible nutrient from the stuff in it they need? Are they possibly just having some mosquito larvae soup to start their day?
