I am very new at raising chickens..I did not even know how they drank water when I started...My question now is, for the last month I have let my hens and rooster free range thru my yard. Well, rooster had to go bye bye, and I have 1 little hen that has been laying an egg..YEAH...but she started laying out in the yard, which I would rather not have her do... So, I have been keeping them in the run area. I have 5 hens and the run area is about 20 x 20...Do chickens have feelings??? Are they happy there, how will I know?
