Will chickens peck at Smartside? How weather resistant is smartside?

I am planning on using Smartside to reside our coop this fall. In fact, it has already been purchased and is in the barn waiting to be used. However, I now find myself having second thoughts about using it. Hence, I am hoping someone can answer any, or all, of these questions for me:

1.) For those of you who have Smartside on the outside of your coop, have you ever had issues with chickens pecking or damaging the backside of the Smartside while they are in the coop?

2.) How well does the backside of the Smartside hold up to moisture? For example, if rain were to get in along a top wall vent, or through a window, would it ruin the Smartside?

3.) If I hose down the coop from the inside, will it damage the Smartside?

4.) Has anyone ever had any issues with a predator getting through Smartside?

Thanks in advance for your help!
