You miss the point...
In order for any type of herbicide to work,,, it must stay residual in the soil
long enough for the plant to take it up...
Dry,,, is fine for above ground grazing(maybe) ,,, but,,, chickens eat dirt, for the gizzard... all birds do...
Besides,,, he will only have a barnyard,,, not a lawn...
2 dogs can make a
barnyard,,, let alone adding chickens, geese,,,and a pig...
