use chiclens to kill grass?

[Rock Home Isle]

I want to use my chickens to kill sections of lawn!
If I leave 13 birds a 20x8 run on the lawn, can I count on them to destroy it?
I know it sounds odd, but it is next to my garden where I want to expand. My pls is to move them yearly to a then different section of garden and allow them to be my weed and feed. Is this practical? Will they do a good job turning that kind of area to wasteland?
Do I need to cut down on the area?
Thank you for dealing with an odd bird.

13 birds should have this done in about a week to 2 weeks, especially if you pen them on the ground so they can focus their attentions....My current garden area is 10 feet by 25 feet and my 6 girls took piles of leaf litter and grass clippings and reduced it to a fine mulch in about 3 or 4 weeks. You have twice as many brids. They will scratch, peck and dig over this area all day everyday. No lawn can take that repeated punishment. Keep them penned over the area and they will turn it to a wasteland in short order.

In early May we had deep litter




Not so much anymore



I'm ready to plant...I just gotta fence my birds OUT of the garden. That'll make 'em happy.
