so i have another construction n00b question pretty please. i want to make that coop door with a plexiglass window. so how do i do that? do i cut grooves in the middle of all the wood frame around it and "sandwich" it in there between the cross of wood on the front and possibly the back of it? or do i just put it behind the wood cross? can i naill or screw in plexiglass? will it break, crack or be damaged? if i can't, then how would i put it in? also, do i need to put hardware cloth behind it to secure the coop from predators or is it predator proof? and also, what thickness should i get it in? thank you so much!
