Pressure treated siding for a coop???? Use or not use?

[RobandSue2]

I am renovating a coop and I went to buy 4 x 8 sheets of PTP to side it when it dawned on me hat it might not be good for the chickens...? Certainly would handle the weather better....but... Anyone?

They would have access to it from the inside btw....

I would not want to use PT wood where they can access it with their beaks, or where it would get wet and water run off would leach the chemicals into the soil.
