Keeping for at least 5 new chicks on Wednesday. Temp is 100 and humditity (yes, I know, lol, but it's what my gma called it) is 58% Tried a dry hatch this time. I have a sponge strategically placed under a small opening in the top of the LG. Should I up the humidity or leave it alone? I don't want drowned chicks, OR shrink wrapped babes.
