I have been reading these message threads here the last few weeks. I am going to build a chicken coop this spring and get some laying chicks when they come into the local feed stores in March. No Roosters. I have too many neighbors close by. I have a little over 1 acre of land and will be placing the coop near the center of our lot. I have a question about my coop design. I found a coop plan online that I like (with a few modifications). The coop is going to be 6' x 10' with 6' x 7' for the chickens and the other 3' x 6' for storage. There will be a hardwall seperating the two areas. It will basically be two sheds back to back. I will also have a large run attached. The plan recommends 3/4" pressure treat plywood for the floor. I am questioning if pressure treat is really necessary. It costs $53.00 a sheet. OUCH!!! I have noticed several people recently mentioning that they use vinyl flooring in their coop. I am thinking of using regular 3/4" plywood and then installing vinyl flooring over it. I thnk the vinyl will keep the floor from rotting. The coop is going to be sitting on concrete blocks. The subfloor will be framed with 2" x 4" pressure treat. The floor joists will probably be spaced 24". I am going to use the deep litter method with pine shavings. I will probably install the vinyl on the floor before I frame the walls. I will also make sure to use a single piece of vinyl with no damage. Has anyone had problems with the chickens pecking at the vinyl flooring? Or any other issues with it? Has anyone had problems with moisture getting under the vinyl? Any thoughts/comments would be appreciated. Note - I do plan to take lots of pictures during and after construction. I will be sharing them here. F.Y.I. - I live in Vancouver Washington (not Canada). I am in the Felida area for those of you familiar with the area. I know that there are at least two other homes less than 1 mile from my home raising chickens and selling eggs. Thanks.
