I never up my humidity. I live in Arkansas and its very humid here. Everytime I followed orders to have humitidy my chicks were dead in the shell. They drowned. Its because as they grow the air cell gets a bit larger if the humidity is too high it will draw water into the air cell and then when they pip... they go for that breath of air and its water instead. If you live in a very humid area or your house has high humidity. I would suggest the humitidy level be at between 45 and 55% no more.
Marans eggs are NOTORIOUS for weak air cells in shipping. If you would like I could send you 2 dozen marans eggs to hatch and the reason I would send so many is because they do not ship well. Out of 5 dozen marans eggs I got about a 24% hatch rate with a 10% live adult. Those adults are doing wonderful. I have since hatched out 30 chick and they are very hardy jumping out of the shell quickly. If you will me email me or join me tonight in byc chat I would be happy to discuss it with you!
