Is cedar safe to build a coop from?

[Gardenofeden6]

I am going to be building a chicken coop and would like to use cedar. I know there are two types. Western red cedar and eastern red cedar. Is one better/safer than the other? I am going to build a quaker style with a walk in door and 2 working windows. 4 X 6 and 6 feet tall.

Any help would be great

Thanks,
