I am increasing my flock to 30 birds and I foresee the need for an automating watering system. Can someone point me to a thread about these or let me know what you are doing? I do have water going to the coop so I could do a low pressure system like I've seen in the McMurray catalog but It would be REALLY helpful if I could do something that would work throughout the winter i.e. circulating the water so it doesn't freeze or heating it. Thankyou!
