Days are getting mighty short, and frozen water bottles are on the horizon. It is time to get out the bowls and be prepared for Ice In The Morning.
A few of the rabbits will see their First Winter. Vanessa, Gunther and Gretchen are all under one year. I am especially vigilant about water for them, as they are still growing and sometimes do not take advantage of the water when I first put it out. Rabbits don't normally need to drink more than once in 24 hours, but they do better eating if they get a few opportunities to fill up. So, I will make sure they get three fresh bowls of water each day for the first two weeks that the temp stays below freezing. Then I will cut it back to twice daily, which is all I offer to the adult rabbits.
Here's a post , with pictures!, from last year, about how I deal with bowls and ice.
If there is ever a problem with food not being eaten during cold weather, the first line of treatment is to increase water and hay while decreasing pelleted food. A stable water supply becomes very important during the winter, and those keeping rabbits outside need to give careful attention to easy ways of dealing with it.
