Hey- we bought our first flock of baby chicks over the weekend and things are going well so far! We're excited about this new part of our lives. What are you thoughts on our 7 hens pooping in our grassy 1/2 acre and kids playing baefoot in the grass? Big problem? Toxic? The hens will be in and out of the coop (when it is time) during the day so i don't know how much of a problem it will be. Thanks in advance for the advice!
