Would running Jerseys (thinking a flock of 25 [poultry crate] next year) in a 3 year old food forest be a great idea to kill off pasture grass, and Canadian Thistle while having them leave rhubarb, and trees alone?
They'll have plenty of wine caps and bugs to eat, so they won't go hungry.
The reason why I'm asking about the largest of chickens is because I need to worry about hawks, and wild dogs.
You can eat anything once, sometimes more than once.
I'm not sure that would quite accomplish what you want, but I think it might be a good idea anyway. Chickens will eat grass, but it is not a large part of their diet, which means in order to kill off the orchard grass, you would need to leave them in one concentrated spot for so long that it would harm the soil structure and soil biology. I'm not sure about rhubarb, but the chickens would not eat the trees, but they would scratch around them a lot. This could cause some damage to the roots on such a young tree. It might not kill it, but I would worry about stunting their growth a bit. You could possibly use electric poultry netting to fence around the trees and keep the chickens safe from predators at the same time. The good part of the chickens would be the manure and the disturbing the soil slightly (move them each day or so, rather than leaving them until the grass is killed) and eating the grubs that would turn into things that would eat the trees or fruit. I believe fall is the best time to de-grub the area with chickens, but again, the killing off of the grass is not something I would suggest using chickens for.
If you just want to keep the grass under control (e.g. mowed), could I suggest geese? They do get the majority of their diet from grass, and would fertilize without scratching. Much less potential damage to the trees.
If you need to kill the grass, I can only suggest either manually cutting the sod off the top or smothering it with cardboard and woodchips.
Every plan is a little cooler if you have a blimp. And a tiny ad.
