Hello! I just purchased my first chicken coop! The inside of the coop is covered with LP TechShield Radiant Barrier in between all studs. Should I paint or cover this? I wasn't sure if the chickens would peck at it and tear it up. If I do plan to cover it, will most paints stick to it?
Have you tried asking the person or company you bought the coop from? If they are in the habit of building chicken coops this way, they may already have the answer.
Failing that, here are my thoughts:
Is that just a thin layer of foil on something solid? Or does it have some kind of foam or fluffy insulation behind it?
If it is just a thin foil layer on a solid surface, it would probably be fine to cover it with plywood as long as you put the plywood tightly against it (no space for the "mouse hotel"
@nuthatched warned about.)
If there is a layer of fluffy insulation or foam, I think it would be a problem to cover it (mouse hotel) and a problem to leave it (chickens pick it apart), and a nuisance to remove it. I can't say which of those would be worst and which would be the least problematic.
I would not expect paint to stick to it, but you could try and see what happens. Paint will not protect it very much, but could make it less shiny, and thus less interesting to the chickens.
When I try to look up whether you can paint it, I find that you are not "supposed" to paint it because then it doesn't work right. You aren't supposed to put anything tightly against it either. But if the options are to do one of those things or rip it out, you aren't getting any real benefit from it in either case, so you might as well go with whichever is easiest for you.
And again, you might try asking whoever built the coop, before you make any firm decisions. Hopefully they know more about the product and its use in chicken coops.
