I hope this is the right place for this question: Say you have 45 square foot per chicken. The land soaks up a little bit more rain that most places (the ground is very low). It usually has thick grass in the spring and fair grass in the summer. There are about 8 young trees (3-4 years old, about 8-10 feet tall). So the question is, what sort of impact would chickens have on that land at 45 square foot per chicken (not counting two square feet per chicken roosting area). Would it be completely eaten up in a week, or completely eaten up in a while. Or, would there be enough space that vegetation doesn't completely die out? Any thoughts?
