First time incubating eggs here 
It's 21 days since I placed my lavender Sussex eggs in.
Initially I had the temp at 36.8 and the humidity was quite high around 70% I managed to get the humidity correct at day 10 and upped the temp to 37.5.
I have candled at 7/14 and day 18 and all had movement and I locked them down.
Some people say not to count the day they go in as day 1?
Would the initial lower temp and higher humidity, delay hatch?
I also now can't get the humidity above 55% and don't want to add to much more water?
Photo isn't great but day 18 candling of one egg, all moving.
