Don't worry about it.Probably being piped from an "artisian well". Lucky horses. That's good tasting water. LOL
I did not mean to panic you with my post, but I have had friends run their well "dry" and it cost them mega bucks for a new one and 3 weeks of carting in every ounce of water they needed for household use until well guy could get the job done. No animals at the time. My chickens use 5 gallons of water a day. I certainly don't want to be carrying that much water in just for the birds.
Someone who knows you/your area commented that you live in a watery area. That can be a mixed blessing. If your water table is normally high, they may not have drilled the well very deep....well drilling is charged by the foot....the fewer feet they have to drill to get an acceptable water flow, the less the job costs. That means that this drought may hit you before it hits those of us who have 300 foot wells because it is going to dry up closer to the surface long before it is going to dry up at 300 feet down. (Remember a drilled well isn't a huge pocket of water just sitting there waiting to be pumped up for use; it is a small area that has to refill from surrounding underground water. When that underground is lower than the depth of the well it won't fill very well, if at all)
There have been a lot of water conserving measured shared here (A couple I am going to impliment myself. Never thought of washer water for irrigation) Pick the ones that work in your life and minimize the unnecessary water useage. I will admit that I can't bring myself to turn the tap totally off when I brush my teeth; I hate to see the toothpaste spit in the sink while I am brushing. But I don't flush away 3 gallons of water every time I use the toilet and try to go upstairs to the newer, more water effiecent toilet when I know I am going to have to flush when I am done. That's a choice I make. Regardless of your water "source" there is limited fresh water on this planet, so we are all responsible for conserving in ways that work in our lives.
Edited to add: Not to meantion that your maintance of your "water system" cost money. The less water you have to process for use, the less you have to spend on whatever your water system required to process your water. (at my house, it's a carbon filter and bleach. LOTS of bleach)

Back to chickens...I'm reading up some pretty horrible stories on here about roosters and how they are behaving with hens. I'm hoping my roo doesn't cause too much too harm to them. He seems pretty good with the 3 girls. Will there ever be a time that I would have to seperate him from them or can he live happily in the coop with them all year round?
