We once tried to raise 700 day old chicks to 13 week free range from January to March, but we had to put so much heat and food into them, and we lost so many of them to the weather, that it was a total loss. I think it cost us about £100 altogether not including our labour. They were a happy little bunch though and 4 of them hid when the catchers came! I'm not kidding you! Seriously - after the lorry had gone, we went in to clean up and found them - one was behind a length of corrugated iron, another was squashed against a stone wall and it was dim so no-one saw her, all we could see was eyes blinking every so often - she was absolutely stock still; the other two had got themselves into an old dog cage that was lying at the back of the shed. So they all stayed and laid lovely eggs for us for years. Here's John with them. They had a huge barn that John renovated for them and an acre of rough grass fenced off.
