The chicks are only 2 weeks old, i have a large chicken house 32' x 16' which the hens have half of it with the orchard outside. The chicks can have the other half, but no outside space. I also have a livestock building 12' x 18'ish which is completly away from the hens. I was not sure which is best, but I would have though that the chicks should be in contact with the hens but kept separated until a good size. Do you agree, Nigel
