Coop door ?

[Aquaman05]

I'm wanting to get the auto door for my coop and was going to use a speed limit sign that's 12x18. Will this size be ok?

Thanks

Do you have Really Big Chickens? Normal size is more like 12"w x 14" or 16" high for large breeds. You can see directions for how to mount a D20 Add-A-Motor on line. Metal blade on a circular saw will make quick work out of sign but, ware long sleeves and googles if you are going to cut it. It will throw little metal sparks.
