Ok, I know I need wire over my windows, I,m just not sure why. Does this serve to keep the chickens from pecking the glass and breaking it or is it purly to keep preditors out. Do chickens peck at glass? Is Glass not used in chicken house contruction or is it ok. Just thought Ide throw this in here. This is Mrs. Nezbit shortly after we got the 4, about 3 weeks ago.
