When I let my chickens out to free range, I have a BR hen that goes out with them for a minute or two and then she goes back in the coop and run for the rest of the day. Is there something wrong with her? The other hens will go back in if they need to lay an egg, but they go back out when they are done. I am just worried about her because she used to go with the others and for the past couple of weeks, she hasn't been doing it.
