Ventilation for 8x16 coop with 20 chickens.

[xSlingsho66]

Will 4 24x24 windows provide enough ventilation, or do i need to start putting slots in the walls, im worried about the winter, Im from Iowa and it gets below 0 very often. The coop is designed where there is really not much options for vents that will not provide drafts, MAY be able to get 6 sq feet MAX of draft free slots, anything else would definatly hit the roosts. Basically Im asking for a rough number of how many square feet of ventillation ill need DURING THE WINTER and another number for summer. (im less worried about the summer, I can always remove the people door and put on a hardware cloth/frame door which would gain 30 sq feet of ventillation.

Do a search for open air poultry houses..you will find a couple of threads and an online link. The book is 100 years old and discusses the need for fresh air, even in the harshest winters..

Sounds like that might do it, if they are high enough. Have you seen Patamdchickens' well known ventilation page?
