Cheapest way to feed free range laying hens?

I used to have only six laying hens and had the same issue. I found one person willing to buy eggs at $3 per dozen once a week. I delivered them to her house a couple streets down. I also sold them to different people in my family. Stop giving away your quality eggs and start selling them. You will make up the feed money and maybe earn a couple bucks. Either way, the eggs you are getting from your girls are better quality than any egg you will find in the store.

Are there any little groceries near you? The nationals are not allowed (rolls eyes) to give away their old produce, rather pay dump fees, but small grocers are more human.
Ask if you can please come a take away all the veggie clippings and culled fruit.

I have 9 layers and use a 50# bag about every 9-10 weeks. and it's always in their hopper, they just prefer to free range.

Is there a grain elevator within reasonable driving distance?  We found a farmer about 13 miles from us who mills his own feed and sells (word of mouth) 100 pounds of layer ration for $16.  You have to return your empty bag when you pick up your next.  I'm amazed at how much your birds eat while also ranging.  We have 5 adullts and 13 chicks who go through aprox. 50 pounds a month.  Good luck!

How much feed they require depends on the quality of what they get while free ranging.  The more bugs, etc., the less feed they will eat.  A nice big pile of mulch of compost is a sure winner for attracting wiggly chicken food.

I also give my birds table scraps.  All those veggies the kids won't eat?  The crust my 3 year old insists be trimmed off her PB&J?  Stale crackers?  Delish!  The birds adore them.  I feel better about not wasting food, and it helps a bit with the feed bill. 

In addition to checking small groceries, you could also look into local bakeries.  They often throw out 2 or 3 day old bread.  they might give it to you or sell it to you quite inexpensively.  I feed white bread VERY sparingly, but you can feed a bit more whole grain.

I go through about that much feed at the same rate, but I have about 45 chickens! They also free range in an area about the same amount of space. I think you maaaaayyy be giving them more than they really need as far as scratch (is cracked corn the same thing?) I dont think I've ever read about anyone doing a 50/50 ratio of that kind. Try a farmers market at the end of the day, the vendors are often eager to get rid of the left overs that wouldnt sell (at a really steep discount), I just cut out the bad parts and feed them to my flock.

Now I'm curious to find out if cracked corn is the same as scratch? If it is, scratch is supposed to be a treat, not a food substitute, and often the chickens will dig through the layena, dumping it on the ground ignored, just to gorge on the scratch. May be you can seperate the feed from the scratch and see how much of each they are eating? Scratch is not very nutritious, its more like candy for them, they dont even need it and can live very happily with out it. Maybe just giving them Layena and no scratch will help costs?

50 pounds + 50 pounds = 100 pounds / 7 birds = 14.29 / 14 days = 1 + pound per chicken each day
50 pounds + 50 pounds = 100 pounds / 7 birds = 14.29 / 21 days = .7 pound per chicken each day

It looks like you are really losing feed and getting ZERO value from your free range. At a pound of feed per bird each day, perhaps you are feeding a LOT of sparrows, mice, or something else -- not just the chickens. Or, they are wasting half of it or more on the ground.

A leghorn-type hen will eat about 1/4 pound of feed each day. A dual-purpose will eat 1/3 to 1/2 pound of feed each day.

Feeding so much cracked corn is not the best way to produce eggs, especially during warm-weather. For the high-protein requirements of a laying hen, the best and least expensive route that I can think of is to go hunting for meat, of just about any sort.
