They never seem to go through the water, it just sits there. I am wondering if it is because they have free range of the backyard are are getting water through the grass and greens they eat outside, or is there something I am doing wrong. The water is in their coop and another in the run and sometimes there is a bucket out in the backyard for them too. I often have to scoop the litter and straw out of the rim of the waterer, but other than that they seem healthy enough. Any suggestions?
