I had a hen go broody a few weeks ago and was sitting on a wooden egg. I don't have a rooster so I got some from a friend who does. 21 days will be Friday, July 17. Last week I found her off the nest and back sitting on the wooden egg. Not sure how long she was off (no longer than 1 day)...
My hen(s) quite laying for about 3 weeks straight. Last week I had 1 egg a day for 3 days and then 1 day I had 2 and then back to 1 the next day. I put a light bulb on a timer in the coop, on at 5 am off at 10. I'm not sure if this is what did it or not.
I'm having the same problem with my hen/rooster. Can't tell which it is. I purchased what I thought were 4 pullets. All are about 20 weeks old now. This week one of them has started "crowing" if you can call it that.
