We are planning a family vacation after the first of the year, but have nobody to tend to the 45 chickens. At best, someone will be able to come once, maybe twice in nine days, and I am needing a plan to have food/water in place even if that falls thru. The food is easy enough. My feeder would hold 30#, so I buy a second one and I'm good. It is the water that worries me, and only because it will need to be heated in a failsafe way. I'll need to find a container for at least 20 gallons (now drinking 2 gal/day), and I am wondering how to heat this...and not just the base. I have electric and water to the coop, and I am willing to do some additional wiring as needed. My plan needs to be up and running ASAP as we leave in 3 weeks so there is little time for trial/error. Suggestions?? Thank you.
