My BIL (husbands brother) has just bought a house that has a ridiculously long garden. All he wants of it is a nice lawned area to sit, and then a place to put his koi pond which will leave approx 60 meters in length spare (from the blue line). He doesn't care about the rest and is happy to offload it onto various family members. He says I can have the last few meters (the last bit from the orange line) to turn into a miniature butterfly and bee meadow. But I'm thinking that I would like chickens now more than a meadow.
Where do I start? Tell me everything you think I need to know about keeping chickens please!
