Ever since we moved the heifers up into the corral so they can calve, we had to move my colts to a bigger pen. This is okay with them, but there is no automatic waterer in there. There is a water trough with a hydrant beside it, so its not too bad especially in the summer, but now the water freezes every night.
So we only fill it a little bit every day and it freezes a little bit so we just put more water on top of the ice. This actually works benificial because there is a hole in the bottom of the trough that is now filled with ice so it doesn't leak any more.
But it means every day I have to go out there and fill it just enough to give them enough water to drink but not too much it will be full before the weather warms up enough to thaw it. It is pretty quick and I am usually only out there just enough time to turn it on and go get oats for them then when I get back to it I can turn it off.
