I am in NYC and have limited space. I have several small breeds and need a good solid way that my chicks can drink, fresh, clean water. I bought a typical water bottle that is used for rabbits or guinea pigs. I was a bit reluctant, but when I placed it in the cage, my chicks drank from it instantly. 5 weeks later it is a dream come true. No mess, no worry about dirty water. I wish someone had suggested this to me from the beginning. Damn, chickens are smart animals. If you are like me and need a good water supply, try it. They come in different sizes. My chicks have fresh clean water every day And, BTW, should you forget to change the water for one day, who cares, it is still fresh and clean.
