I live in Arkansas and it is very humid. Even with no water in my incubator the humidity keeps jumping into the 60s. I've tried unplugging the little plugs, plugging them back in. Doesn't really matter. What will happen if I can't keep the humidity lower? Will this mess with their air sac?They are on day 7 of incubation. Also, I have a few of my shipped Welsummer eggs that have a saddle shaped air sac. Any tips on what I should do differently for those?
