I read somewhere on the site that cedar is toxic to chickens but I have a noble fir christmas tree...and I want to know about the advisability of using the trunk as a roosting pole AND if I can use the boughs in their nesting boxes (underneath hay) and elsewhere in the coop for their comfort and amusement? Secondly, do they HAVE to roost for their health? I have one rode island red hen who just prefers sleeping in a nesting box. I am re-building their coop, and I could use the opportunity to force her to roost by denying her any other option but this is not my instinct. If she has access and choices and she just prefers to sleep lying down, is this a problem? Thank you! I love this site. I love my chickens!
