You guys were all such a help, and told me that I could put 2 silkie hens in the single horizen shipping box. I had recieved my 2 polish hens in it previously the year before. I know you put shavings in the bottom, but what do you guys usually use for a water source? Fruits, veggies? I heard some people put in a damp sponge for moisture? Any help would be appreciated!! Thanks so much!
