    I think the biggest one would be smell.

    If you stick your head in and say "hmm, I think animals live in here" then you're good.
    If you stick your head in and the smell knocks your socks off then you've got problems.

    I think humidity is another thing, but that can be a bit hard to judge in Arkansas [​IMG]

    Maybe someone else can tell you better.

    See my Ventilation page (link in .sig below) for a lot more info on the subject [​IMG]... but, as far as signs, I would say the big three (in no particular order b/c importance varies with the season) are

    -- if coop smells "strong" when you go out there in the morning and open the door, you need more ventilation.

    -- if there is condensate or frost forming on the windows etc overnight, you probably need more ventilation. I say "probably" because in extremely cold climates, frosted windows may be inevitable because of the huge temperature difference in vs out and may not reflect a real ventilation problem. But if you can walk out to the coop with bare flesh exposed for more than a minute or two, then if there is much condensate on your windows you need more ventilation. (Condensation/frost on coop ceiling or walls means a severe ventilation deficiency, EXCEPT that in a drippy ceiling may also require insulation in cold climates)

    -- if the coop is still uncomfortably hot, like quite noticeably hotter than outdoors, an hour after the sun goes down in the summer, it needs a lot more ventilation.

    GOod luck, have fun,
