I live in Sydney Australia so I am moving into summer. I have about 120 sq metres of lawn that I can separate the 3 chickens into two areas for long periods. I have winter grass coming through my Buffalo lawn. The only real solutions I know to try and eradicate the winter grass are using a herbicide such as Amgrow next March and April or to re turf the lawn - though this is not guaranteed as I do not want to kill the entire lawn using Roundup first. Re turfing is expensive but the Buffalo grass is getting near to the end of it's life - I think.
The question is whether anyone else has used a product like Amgrow and whether it is safe to let my girls out into the treated area after 4 weeks or is there another solution. We also use the eggs and give the excess to next door neighbours.
