I looked after four chickens when I was about 10 years old. It was my job to clean them out, which I did daily and to keep them fed and with clean water. They had a cage type thing in the garden but they were left to walk around the garden each day, I only put them back in their cage (which was enormous) at night before I went to bed. If I remember rightly, they had a closed in bit of their run which they could go in to be in the dark. I learned lots from them like tolerance, patience and all the usual things you are able to learn from looking after animals. I recall that I had to put vaseline on their feet as they used to what my Dad called cramp, but I don't know what the problem was, I was only a child.
