I am clearing Wandering Jew (Tradescantia fluminensis) from Unsworth Reserve. This stuff has not been sprayed by the council. Do you want some for your chickens? They are talking about it being good stuff for chickens in the Ooooby Poultry in Urbania group. Plus you would be doing me a faviour by getting rid of it. Just drop by a bin and I will fill it up for you.
You can also get it in Exster Reserve (which I will look at cleaning out latter) but I don't know if that has been sprayed or not.
