Yeah i wouldn't put salt or sugar in their water. Even if it was safe i don't see my chickens drinking it they are really picky. I have been putting bottles of salt water in with securely screwed on caps so nothing leaks, and that worked for a while but it's gotten really cold the past few days. That sounds like a really viable option, is there any chance it could burn my birds? I have a roo who hasn't quite matured yet and the girls are giving him a hard time, he bumps into the hanging waters all the time and then i need to go out and dry him off so he doesn't get too cold. I don't want to add burns to my list of possible injuries in my flock.
