We have 2 cochin hens, they have been laying eggs now for a couple of months. 3 days ago we noticed the 2 cochins were staying in the nexting boxes all day, so we just figured they were going broody and sitting on eggs. Well today we were gonna check and see how many they were sitting on a mark them.. but neither are sitting on any eggs... Is this normal behavior?.. The rest of my flock are acting totally normal and seem fine.... These are my only 2 cochins in our flock.
