I have 6 chickens that came to us in the weirdest way.
In March of this year my brother-in-law found two baby chicks hiding in the bushes in the front yard one night. He decided to keep them because my nieces fell in love with them, and also because we'd often find dead chicks outside. There was a flock that belonged to a neighbor who'd let them free in the street, so we kept those two chicks instead of releasing them back to the street flock.
A week or two later a tiny chick got into our backyard. I was home and heard it, poor thing was dirty and smelly, and had some blood on its beak. Thus two chicks became three. So far they are mystery breed chickens.
A couple of months later our chicks turned into pullets, so we have Megatron, Godzilla, and Rusty. My BiL wanted to get a rooster for the pullets, and I knew a lady from another forum got a bit too many cockerels in this year's hatching, so we adopted one, a light brahma named Roostroyer.
A couple of months later, we see a cute barred plymouth rock hen at the feed store so we took her home, she became Spaghetti aka grumpy lady.
Remember the neighbor with the street flock? He moved away and is selling his house, and took most of his chickens with him. Four hens were left behind, and two weeks ago one of them fell into our live trap. She because Dust, and my BiL has been trying to catch the other three hens that are still roaming outside. funny how we don't look for pets, they come to us XD.
