Hi, all my girls are allowed to live out their natural lives on my farm. I have 5 hens who are 10 years old. Contrary to popular belief they still lay eggs. Its not as often but I can usually count on about 2-3 eggs from each of them a week. That's not bad for an old bird.
I have found that my older girls make great pets. They are lovable and make great mothers. They even teach the new comers that I order how to be chickens. When they no longer lay they are still very valuable but in a different way.
They don't lay as often or even as much as they used to, but at the ripe old age of 10 I am still getting good quality eggs from them. I plan to allow them to live their twilight years on my farm as long as they still have the desire to live. If they start to fail due to their age I will cull to keep them from suffering. But for now they have a zest for life and are enjoying their setting sun years on my farm dust bathing, catching bugs and sunbathing.
Most chickens do not make it to 10 years. They are a rare bunch of special ladies. Their rooster has long since passed away, they have outlives many of their flock mates. So they have a new rooster that takes really good care of them. They are a delightful bunch of girls to have and care for.
The original Buff Orphingtons, my fabulous 5 are apart of this group. The others have long since passes, but my fabulous 5 still carry on in their absence.
The older girls meeting the new ladies no the block.
The fabulous 5!! Minus the photo bomb of Athena the White Crested Polish.

Enigma the Motted Cochin is their caretaking rooster.
