Hi!!! I am new to all this and just put my first dozen in the incubator. Its running at 40% humidity and 99.5 F. The eggs were from a local gal that collected them for me and they are 3 days old at the most.. I weighed them and marked the air cells. They were kind of dirty but I put them in anyway. The air cells are all about the size of a dime but I had one Marans egg that I couldn't detect the air cell.
I decided to incubate eggs after having a few chicks starve out after receiving them in the mail. I have 9 chics now but I couldn't see ordering a minimum of 25 so here I go!
Hopefully I can be successful with my first hatch. I am using a hovibator with the #3 water trough filled. Running it dry it was only at 15%.
Wish me luck and pour on the advice.
Welcome @2FunKids sounds like you did your homework! you have your thermo/hygros calibrated and all that? sounds like your set, 40% sounds a tad high to me I would run around 30-35% if your calibrated. no lower than 99.5% I like to run at 100 degree... Glad your with us!! what kinda flock do you have now?
