If your hens have clutches that hatch late in fall or super early in spring you may find this article interesting. This little broody Cochin hen actually adopted some chicks to keep warm when the weather turned cold and wet. She keeps them warm and forages with them during the day.
The article is from The Holistic Hen and I find the entire site interesting. They have free range poultry and they call it a forest garden and the chicken roost in the trees at night. They also have quail and a variety of chicken breeds. All raised organically. It is interesting to read about the ways that are different and even the ones that are the same as what we normally see in chickens. They seem to really see all the unique personalities of their chickens which is really neat.
