We have free range chickens, sometimes too free range...they have found many ways around the no climb fencing and into the lawn which isn't a problem for me (don't ask my husband he may not agree) but he did bring up a good point. Typically in the spring we spray for weeds and use fertilizer how can this be accomplished w/ chickens? How long would they need to be pinned before they could walk on the lawn if any? Anyone heard of chickens dying from being in a yard where weed killer or fertilizer was used? Thanks in advance for all the advice. This website is great! -Cortney
