We used to know a guy who wanted as many chickens as he can get, so he can sell eggs, but he didn't care for them as well as he could've... He used to bring his sick chickens round to me. He'd walk in the door, hand me a chicken, turn around and walk out again, shouting over his shoulder: "if she gets better you can keep her" Well, the first one, Hope, sadly didn't make it, but the next two, Faith and Luna did.
Then a predator got Faith
It was devastating after the battle to get her better.
Luna grew up, went broody, hatched chicks and had a wonderful time by us. She was a great mom and she beat up a huge hawk one day when it went her chicks! We absolutely adored our Lunatic.
Our other free chicken was from a friend. He came round one day to buy hatching eggs from me and I just happened to have one from my old Australorp X hen who still laid very well aged 5/6 years. I told him I hope that egg hatches for him as it's from a very, very good hen. The egg did hatch and he gave me the chick, because, he said, he could tell her mom is special for us, so we must raise her babies.
