We have three foot hay on part of our land (short version is that someone planted on it without our permission). We are looking at farm tractors but for the short term, my gorgeous DH is building some chicken tractors so that the hens can help us out. We plan to drag the tractors around the field and see if they can help. What do you think? Are they going to be able to do much to clear the field in the next three months? It's less than a half acre and we have 16 hens and one guinea hen in three tractors.
