My hen began laying eggs about 3 weeks ago, but no signs of brooding. I've left many of her eggs in her nesting box to encourage her to hatch them. I know many breeds do not go broody, but I think my hen is a buff orpington which are known to go broody. Anyone have any suggestions on how I can encourage her go broody? Is she truly a buff orpington? She looks darker than the pictures I've seen of buff orpingtons online. Here are some pics.
