Laying hen has been staying in the nest boxes all day and not laying. She's our brown Egger and used to be the most eager friendly yet dominate in a mother hen way. Now she just sits in there and doesn't even seem interested in meal worm treat time. I'm worried she's not eating or drinking enough. And no eggs in five days but she's very interested in sitting on the other eggs and gets aggravating when we remove them. This behavior we believe began when we introduced ceramic eggs to the boxes to encourage the hens to use the other boxes since they (4 others) were all using the same one and we have 3 more that should start laying soon. It worked and they started to spread out but I did notice some egg stealing going on when they were in there together. We don't have a rooster or fertilized eggs. Is there anything wrong with Mama Birdie besides that I should just lock them out of the nest boxes after they lay. Which is not easy since they don't all lay until noon.
