So I walked out to feed my chickens today and found that another one of my leghorns has drowned. My garden hose has been frozen for a week or so, which is unusual where i live (SC), so I have kept my 15 gallon kettle out to keep liquid water around. It freezes over, but a little work with the garden tools and I break the ice and get the liquid out from inside to water the flock. Today the kettle completely thawed and i went out to find one of my Leghorns dead in the water. It isn't the first time that this has happened, but it is always a Leghorn that it happens to. 5 out of 10 leghorns drowned in water throats in a flock of 23 chickens total. The flock is a mix of golden comets, easter eggers, and silkies. This makes me want to steer clear of this breed next year, which is too bad because they give me more eggs than i could ever use. Any opinions or alternatives? Also the kettle stays in the shed when i don't need water storage like this.
