When installing 2 gable vents, is it better to have one side draw outside air in and the other side push the inside air out creating a cross flow through the attic, or better just to have both power vents pushing air out?
If your horses have a place to get out of the wind, they should be fineMy horses are and the actual temperature (not wind chill) was -15F this morningHaving free range hay is the best thing they can have in cold weatherDigesting hay helps keep them warm.
If you install them both blowing out, you are looking at problemsThey are rated to move a certain amount of Cubic Feet per Minute (CFM)If they are working against each other, the soffit vents will not provide enough airflow to accomodate them both, causing them to overwork themselves and overheatNot to mention, if they have a high CFM, your attic hole panel may lift and release your cool air from your houseIf you are not running air conditioning, I would suggest an attic hole fan blowing into the attic and drawing cool evening air into your house through the windowsThis is what I am using right now and I am usually wearing a long-sleeved flannel shirt until about 9:00 am, and I live in Florida! Getting back on pointIf you are going to use two gable vents, they need to work togetherFigure out which way the wind usually blows from during the summer and have that vent blowing in, with the other one blowing out with the windThis way, the fans will not overwork themselves, and the wind will flow right through them, keeping your attic coolI am assuming that they will be installed with thermostatsYou can posssibly hook them up to the same thermostat so that they work together more efficientlyYou might want to secure your insulation on the incoming end of your houseI hope this helps!
Get them winter blankets or if possible, for a place for them to stay inEven if they have the thickest of coats, that doesn't mean they're always going to be able to handle the coldUnless they come a breed that originated from Alaska or other cold parts But give them winter blankets that are water proof! You don't want the snow melting or water getting through and making them colder.
Definitely add salt to their grain to make sure they drink enough water, to avoid impaction colic2T 2x per day will workNon iodine salt.
If you blanket them, they'll shed as the temperature varies and when you take it off, they'll be coldThe best thing you can do is ensure they have plenty of high fiber content food (hay) to keep them warm by digesting, make sure they have shelter from wind and drifting snow, and check 2-4 times daily to make sure their water source hasn't frozen overAdding a dash of table salt in their feed doesn't hurt either, to make sure they don't get dehydratedDehydration can be as common in the cold as it is when it's hot out.
