I'd like to know what kind of wood to use for my chicken coop. Well we used treated for our posts ( ours is off the ground 2.5') and for the floor framing.
This includes what type of wood. Construction grade. (that's usually pine)
Whether it should be painted or not. Paint or a sealant would help with bugs later, or if you use a cheaper grade of plywood and have to seal it up. (my concern with paint is when it starts to chip off and they eat it) I have heard of people using linseed oil to seal the wood.
And whether it should be treated or not. I feel that if any wood is in contact with the ground/weather it should be treated. but this is just my opinion. others won't use treated at all. Your decision.
Also, do your chickens pick at the wood at all? I did not use treated wood for the plywood floor. and the wall framing. I don't think they will pick at the wood just to eat the wood. maybe to get a bug or 2.
Thanks Good Luck with your decisions.
