as a newbie to hatching turkey i can say in the little giant i had zero hatch...at the last min with the last egg i took it to a broody chicken and it hatched and is well and almost 8 months old now...with a sportsman i am in the middle of a hatch now and so far i have 50% hatched..i did not raise humidity, but i am in the south and it has been plenty humid naturaly. i hatch chickens and ducks with no problems..just as said already remove little faces as they hatch. i have been on pins and needles awaiting the turkeys though because of problems last year. from the one i hatched last year and the ones i have bought as babies i have lost none..i do not measure temp in brooder, i just let them tell me what is right. today i have had one hatch that wasnt right in the tummy area atached to the egg membrane, didnt know what to do so i put glue on it and held it till it dried hard and didnt let it's intestines hang out, dont know if that was a good thing to do or not, looks good for the moment but i guess time will tell if it can eat and digest and live. guess things happen with every hatch and this tummy thing was just one of those things, i done what i could with the knowledge i had and will just let time tell. good luck. hope all goes well.
