Exactly. More birds will clear it quicker, but you also have to have a place for the birds to go to after they are done working that area. If you have acres to work with then you could probably clear it in such a way that as you clear the last piece of land, you also harvest the birds.
Let's say you have a piece of land that you want to clear for a food forest AND you also want to raise a flock of meat birds. For sake of argument let's also say that the birds will spend 12 weeks on pasture.
Take the total area to be cleared, divide by 12 (weeks). Then calculate how many birds it would take to clear ONE section of that pasture in 7 days. That is the number of birds you should raise.
I figure they won't likely clear each section at the same rate. Younger birds won't eat as much and they won't be as efficient at scratching so the first areas may take longer to clear. Then again, as the season progresses there will be more vegetation in those areas yet to be Chicken-tilled. Anyway you want enough birds to overwhelm the area you wish to clear.
