You better also get the metronidazole. If you can't afford it, just PM your address to me and I'll mail you some pills for free.I got safe guard. Once they are old enough to start worming I will start worming them but I'm going to have them in my room for a few weeks then move them to a brooder and then eventually the ground. I don't pay attention to the humidity I just keep the part were it holds water I keep it full of water. Usually when I hatch out chicks that have dates apart I just move the egg away from the hatching egg and try and keep the chick from scrambling the others.
So you have no idea what your humidity is then, right?
