I had access to plenty of 5 gallon buckets, so here is what I am trying out.. I cut lids about 1/3 to retain the hay or in this case shavings, bored some holes on the down side of the bucket to drain any moisture or fine dust. I key holed the back of the bucket in two spot in a vertical line to mount the buckets to the backboard, to allow for quick removal for cleaning. Mounted perch boards for the girls easy entry and exit. 15 buckets total mounted in a frame that someone junked that held and old projection tv. House is also made from 40x48 shipping pallets.
We took some Sterlite totes and mounted them on the wall. I had a bunch of them just laying around empty after a yard sale and my husband asked if I could use them for anything. My girls just started laying a few weeks ago and I had dish pans in the coop for them lol. I think they like these better! I have 35+ hens so I mounted 9 totes on the walls. I have one that just started laying last week and likes to do so on the floor so I put one tote on the floor.
My oldest ones are still about a month away from egg laying. So most of the ones that I have put in there to introduced them to the boxes did well. A couple of the high strung ones did not stay long, a little bit of slipping getting out in a hurry. They appear to be getting in at night by the looks of the shavings when I let them out in the morning. Time will tell.
