Hi. I don't have chickens. I have Indian runner ducks and Toulouse geese. I hope that's okay. I found this site when I was having trouble incubating goose eggs. There is a ten year old article here that has helped me go from zero hatches to 100% I've had ducks for about five years and geese for maybe two and a half years. There doesn't seem to be as much easily accessed information about ducks and geese as there is for chickens. So, thank you for those postings.
