Sorry to hear about your RIR. I have gotten to the point that if a bird gets sick, I know it will die. I have yet to save one. Not that I don't try, I just prepare myself and my kids for the worst.
Battened down the hatches in the coop for the coming snow. Food, water, straw, shavings, etc. all resupplied. The chickens have been out all day enjoying the yard. I figured they won't come out for a month once the snow hits so they better enjoy it while they can.
The hygrometer says my incubator is setting at 28% humidity. That's way too low. I have a bowl of water in it too. I am going to add a wet wash cloth to see if that helps. I guess this could explain why we are not hatching. The temperature is good though.
