Now i know this question has been asked a lot, but mine is slightly different. I am currently incubating silkie and orpington eggs and have a humidity set at 45%. I have read on the web that it needs to be around 50%? What i want to know is after 7 days of incubating them can you alter the humidity up to 50% for example. Or does it need to be kept constant? Also what humidity for the last 3 days? I know people say 70-80% but again since mine is at 45% what is advisable to increase the humidity to? Any help would be great thanks.
