I have this chicken that used to go to bed every night in the coop. Two nights ago I noticed she was missing. I scoured the property and eventually found her in this little spot sitting on top of one egg. It was probably 90 minutes after she normally would have gone to bed. Again last night it was well past time for all the chickens to be in the coop but she was back in that same spot sitting on that egg. Is it possible she is going broody? My rooster was killed by a coyote and I have no mature roosters around that are mating with the hens. Anyone know what might be going on?
