what day are you ? Lock down on day 18.
I cant give advise, Mine are doing terrible. Sallys thread is great for this. Pics help a lot too.
Today is day 17. I set on 2/27 around 1pm. Pointy end is clear. Chick is laying in the middle with one leg up toward the air sac. He was going wild earlier. I can go back down and try to get pics but they might not show much.
