My gardeners put out fertilizer against our wishes on Thursday. How long before it's safe for the hens to roam again? Yes, I'm livid. My husband was able to round them up and get them into their coop before any of them ingested it. They do not spend much of their time in the lawn, but they run across it to access the garden and get to the other side. ;-) anyway, it has drizzled out but should we just wait until after the big rain next week? I was going to let them out today but hub thinks it's unsafe.
