I just planted new grass in the chicken run. I noticed the bag says that the seed is treated and it shouldn't be used for feed. I keep the chickens out of the areas that I plant until the grass is at least 4 inches tall. Does anyone know if this is going to hurt the birds? I planted grass twice last year since I have the ability to keep the chickens out of certain patches for months at a time until grass grows back. The previous bags of grass were similar but I never read any warnings on the bag until now. Does anyone have recommendations on something else that is safer to plant? Will grass from treated seeds cause chickens to get sick?
