One of our hens (less than one year old) plucked her chest and started to sit in the egg box a lot. We left her eggs and she seemed to be getting ready to sit. So we seperated her from the others and gave her a small coop. But she didnt like it and would sit as close to the fence where the others were as she could.....in the rain and snow! So i felt sorry for her so moved her and her eggs back. Now a different hen (also the same age) has also plucked and is now sitting on the eggs! She is in there a lot, not laying anymore. But when ever i go out, she comes running out the coop with the others to see me/the treats i bring. When i feel the eggs they are always warm. So, question is, does she know what she is doing? I thought they wouldnt leave the eggs more than once a day...but she doesnt seem that committed...... but as i say, the eggs are always warm.
