No cedar as bedding but what about as a building medium?

[Emilys3guppies]

Can I use a large cedar dog house as small henhouse? Is there any way to seal it so it's safe or should we just steer clear of it in any form?

Thanks!

Its not an issue if its vented. Boards don't put off as much fumes as shavings.
