I have 6 hens. One is broody and is in the favorite nesting box. We only get one or two eggs each day from the rest since she has become broody. The others don't like her in their nest box which they usually all use. There has been no other changes in food, etc. Do you think this is the cause of less eggs? Or, maybe due to the long winter rains here in Northern Calif? We're puzzled.
