# How many chickens does it take...

I thought this would be the best place to post this, not sure though. Is there a mathematical formula for how many free range chickens are needed to keep a certain square footage of grass "clipped" at a certain length. Something like:

X/Y/B=C

X= sq ft of grass
Y= inches of grass height desired
B= Average amount of grass a free range chicken eats
C= # of chickens

I know that the example formula I gave probably wouldn't work, since Pi is not in it, and nothing is squared
But you get my point.

Reason I ask is we noticed that our 3 week old chicks keep the grass in their 64sqft run at about 1/2 an inch tall. They are in there from about 8am until dark. The rest of the yard is about ready to be mowed and is several inches tall. We looked at it today and said cool, then scratched our heads, and said to one another at the same time, how many adult chickens do we need to keep the rest of the yard "mowed", but not dirt.

So anybody have any formula?

Not really sure. I put 28 chickens at 14wks old in a 256 sq ft run and in 2wks there wasn't any grass.

Not really sure. I put 28 chickens at 6 wks old in a 256 sq ft run and in 2wks there wasn't any grass.

That is a tough one with more variables and results. They will dig, scratch, and trample in addition to clipping.

They also fertilize while they are at it which will promote growth and maybe even kill the grass from overfertilization.

If I ever get my orchard fenced I can give you a qualitative rather than a quantitative answer.

Our backyard is fenced with an 8' privacy fence and is about 1/3 acre so our 10 probably won't make a dent in it.

My backyard is quite small as my entire lot is just 0.10 acre. I don't have a lot of grass because I am an avid gardener. With 4 chooks and the little grass I do have, they've kept it clipped all summer. I haven't mowed it once.

Here's the google map of my house. You can see that I've got a very small lot!

JeensPeeps, that map thingy is too cool! How do you do that?

My hens will be out in the run by the end of three weeks (dh said it will be done by then) so I can' help right now! My chickies are runlessat the moment.

Edited .... typos!!!
