I built a nice size run that is about 25' x 30' This year. It has worked great for 15 chickens all summer and the vegetation has flourished all year. This gives me over 50 s/f per bird and they had plenty of clover/grass all summer. So as winter approaches I am concerned that this run will not get the boost its needs to maintain vegetation all summer next year without a break during the fall/winter... aside from building a whole new winter run what can I do? Will they pick it clean now that the fall/winter is creeping up on us? Any chance Im wrong?
