I finally got to look at my seramas nest today that she has been sitting on for a couple weeks. I had noticed the younger hen sitting with her alot. Thought she was keeping warm. I was shocked when I saw 12 eggs today that were two different sizes. I candled them and the bigger ones are almost ready and the little ones are just starting. What happens when the older batch hatches and the new batch isn't ready? Will the younger hen stay on them or do I have to incubate them?
