My flock is "free range extreme", they have 270 feet by 180 feet, a little under half of this is a cultivated field and the rest is grass pasture with trees. Most of the time the flock is entirely on it's own without contact with humans. I started out with 9 green legged partridge hens and one rooster (this is an eastern european heritage breed, because I live in Poland). I added two white leghorn hens shortly after. then, across the course of three months, several of the green legs got sick and died, so when one of the hens went broody I collected some eggs from a neighbour and raised another 9 mixed breed hens. All of these 9 hens are still alive and are about 2 months old now, 3 of them are actually a broiler breed. (I put 6 eggs under the hen, only two hatched so I quickly rushed to the breeder and bought 7 one day old chicks, and placed them under mommy - she accepted them). however, in the meantime, one of my green legs roamed off (jumped the 9 foot fence to roam as usual and then never came back one day), and over the course of 3 or 4 months three of the green legs got taken by hawks, even though most of the time the flock hides under the trees to escape heat and predators. Setting aside the ones that got sick, I have thus lost 4 green leg hens over the course of 5 months. three to predators and 1 to roaming. This is not so bad, I can easily raise many more than this each year by having one of the broody hens raise a clutch of her eggs. I don't use a brooder, I let the hens raise the young themselves and it works very well. the question is, considering that these hens are pretty much wild and range over a large area on their own, is a loss rate of just under 1 hen per month normal and acceptable in an extreme free range condition? Note that only that one hen used to roam; the rest of them seem to know that they are safer staying on the property so they don't roam. I hope that this loss rate is normal (it's my first year with chickens), because I am not willing to confine them. the quality of the eggs would drop.
