I had a flock of 4 chickens. 2 of them turned out to be roosters. I gave them away. I had 2 barred rock hens left. They are about 1.5 years old. We left for vacation and our neighbor who was watching them and collecing the eggs called and said that one had passed away. Just basically looked like it had a hear attack and was face first into her nest. The other one was still happy and laying when we were gone and after we got home. Where we live, you can only get chickens for about 2 months and we were past this time to get her a new friend and the pounds only have roosters available. She seemed fine and we decided to get some more friends for her after this coming winter. Today,I went out to check on her again like I do every day. She is just sitting on the fake layer eggs and is now on day 3 of not laying. I have to now coach her out of the coop to come get water and food. Is she just lonely or do you think there is something else wrong with her? She still looks really good, super friendly, no feather loss and when I present food (treats) to her she goes for it like normal. We Live in Northern CA and the last week it has been 98+ degrees each day. Any suggestions...I am at a loss
