What is the Definition of a Draft in a coop.

Well, they've been modified in some way or we wouldn't have so many recognized breeds out there.

They are not 'modified' as in GMO.

Breeds were created the old fashioned way,
cross breeding by regular old physical sexual mating.

Chickens have been crossbred both intentionally and unintentionally for hundreds of years....just like dogs.

Sorry, my terminology was incorrect, but I think you know what I was trying to say.

I wasn't sure, and others may have not either (easy to panic riff off those 3 letters/words-GMO), so wanted to clarify.

I have GMO birds !


Giant Meddling Offenders !

They always have to get in the way and think they can do better

I have a question which came to mind from this thread. My coop sits with the back to the north and the front to the south. It has a peaked roof with the rafters also in that north-south orientation. I was thinking of screening the gables with 1/4" hardware cloth, but, do I want a vent on that north side in the winter? There will be a fairly large screened vent on the south side at the top.
Just for reference, this winter we had a low of -29 and several days between that temp and zero. We also have some very windy, snow-blowing type days too.

Confused.....if rafters are on N-S line, gable ends would be E&W and eaves would be on N&S??
Regardless...it might depend......
-how close roost is to vent.
-just how much air blows in thru vent in winter.
Ventilation is tricky and hard to assess online, there are many variables to each coop and site. Best to stand inside coop on windy day and 'feel' where air is moving and how strongly. Good to go with lots of venting that can also be dampered or blocked/closed if needed.

My windows are open all summer, shut in winter. Eaves are open all year round, but I do add a block(large piece of cardboard on top of coop 'ceiling') over roosts because they are near(~2-3' below) the north eave. These rafters run on a N-S line, if I didn't have that 'ceiling', I would tack cardboard on bottom of rafters from top of north wall to about 2-3' up to direct air flow above roost.

Yes, rafters run N-S, eave ends are E-W. I hadn't thought of adding a baffle to direct the airflow higher, but I will do that. The coop walls are only 4 feet high, so getting the flow above the roosts will be easier that way.

Let's use a labeled pic to make sure we are using the same terms.
Red lines are rafters.

 

[kklowell]

Yep

 

[aart]

Yep

OK, Then....

Yes, rafters run N-S, eave ends are E-W.

I think you have 'gable' and 'eave' reversed.
.....your eaves are N&S and your gables are E&W.
