Should I be worried? I am new to the chicken world and have had my red production pullets for only a few days now. They are about 12 weeks old. I bought them from my local feed store. The area they were contained in at the feed store was a shaded area. Since I have brought them home, I am noticing that my chickens will not venture into the sun...They will literally stand in the same location all day until more shade is created as the day progresses. This worries me for their future egg laying capacity, as sun is a requirement (so I have read). Should I be worried? Is this a normal chicken behavior? any advice/reassurance will be much appreciated.
