Hi I'm currently incubating 14 Indian Runner Duck Eggs at a temperature of 37.5 degrees centigrade. It is wetbulb. It is a very hot day and I would like the humidity to be around 55% but I can't get it to go below 60%. It is currently 63% and I'm very worried as I candled them last night and they were all doing great. I have taken water out and added water but it won't go below 60%. Please help me sort this problem out. I really don't want to lose my ducklings!
