I am going to use on old coop and fix it up some. I got 12 totes i think they are 4 gallon toes that i am going to cut a hole in, i saw this made on a show on TV. Then sit them on a shelf off the ground. I was thinking the front lip so eggs dont roll out, should it be 1 inch or 2 inches you think? or instead of leaving a plastic lip run a 1x1 across the front of them all to help hold them in place and to catch the eggs too? any ideas? Working on this last part this weekend.
