Hey guys, I have around 20 chicken eggs in a hovabator. I am on day 17. Ive noticed that the humidity in my incubator has risen to over 60 in the last couple of days. I dont understand this as i havent added any water as the atmospheric humidity here is already high. I have candled a few eggs and there seems to be atleast 6-7 embryos developing fine, atleast. Can anyone give an explanation to this phenomenon?
