Have you ever done a tile floor? I've done three in my house. It is a labor intensive job. Unless you already have a concrete floor in the coop, you can't just mix some mortar, and slap down some tiles. Gotta have a strong subfloor (No flex), then cement backer board, or Ditra, then mixing mortar and putting down the tiles. Then mixing and slathering down the grout. A lot of labor, time, and expense, for a chicken coop.
If you have a wood floor, save a lot of time and effort, and buy a bucket of Blackjack #57 (From Lowes). It's a rubberized roof coat product With linoleum, or vinyl, there is cutting and fitting, and gluing or nailing involved. With the Blackjack, just stir well (MOST IMPORTANT), then just dump out on the floor, and spread out a heavy coat with a roller. It totally seals the floor, floor joints, and the gap where the floor meets the walls, under a rubber skin. I've had this stuff down in my coop for over 6 yrs, and it pretty much looks just like it did, when I first put it down. It has seen temps from below 0, to over 100 F. Unlike linoleum, or vinyl, it becomes a permanent part of the floor. Nothing can get under it. Vinyl and linoleum will eventually crack, split and fail in a coop. Then you will have the crappy job of pulling that chicken decorated junk out of your coop, and cutting and fitting the replacement junk. Linoleum and vinyl are made to be installed in a climate controlled house/building. Not a chicken coop, with the wiiiide range of conditions and temps, ect. it will see.
