Hi, I've been incubating chicken eggs for about 11 days now. I candled them tonight and all of them seem to be doing great, big veins, the air sac its also perfectly normal. One thing that I do notice is that while I'm candling the eggs, I do see the chicks move but they don't move that much. I have seen a lot of videos of candling chicken eggs and their chicks move a lot inside the egg and they are really active. Should I be concerned? I do know that they're alive and developing though.
