I let my birds out every day to roam in the pasture. In the evenings when I collect the eggs, everyone gets treats, they come running when they see me with their treat bucket and go right into their pens for their treats.
We lost our water a few days ago. Our pump died. My biggest concern was water for the birds. I took a large trash can cleaned it out at my neighbors and filled it with water. We had a hole in it because we had used it in the past for water. All of my coops have auto waterers. We let gravity work for us and the birds waterers had water. We were without water for a few days.
Hurricanes have knocked out our pressure tank - no water. I have two wells so was able to have water for the horses and others but no water in the house. We have since built a very strong structure over the well area that serves the house and cut down trees that may fall on it. The other thing I did - I put in an old-fashioned hand pump. No electricity or pump or pressure tank needed!
