Good day to all, After reading some on humidity and frostbite due to lack of ventilation in the coop, can someone tell me if we will be ok? 16hrs till we transfer them out to the coop in east-central Ohio. Building is a 20x40' coop with the new coop being in a corner and 5x7'. Ceiling in the corner coop is 4.5' in the rear and 7' in the front. Venting is limited for winter, 2 125w heat lamps. Granny says we need to put plastic on the outside of the netting to keep in warmth but after reading on this site I am questioning it... Also, I plan to seal the rear vent seen in the pic, maybe this should be left open? Hope pics help, thanks for any advice for our cute new chicks.
