I have two coops...they are linked by a run. The chicks are in one and I have two hens in the other... I am using the large, metal waterers for both but the hens seem to kick up and move around the bedding a great deal. The waterer is getting lost in shavings and spilling when they unearth a section of shavings. I've filled it up multiple times today, their coop is going to get nasty and I'm worried about them not having access to it when they fill it with shavings. Where should I put it?
