That's the only way to do it. I learn something new with every hatch.I can't wait for the hatch. I am excited. I hope all goes well. I will take the lessons I learnt from this hatch and use it while incubating the guinea fowl eggs in the near future. Hopefully, I will be able to control humidity as it will be in the rainy season which is when guinea fowls lay eggs.
I'm sure someone here will be able to give you some ideas for the humidity issue. I don't usually have a problem with humidity in my incubator so I've no suggestions...
Oh I'd love to see pics of them if you can post some. What color are they?I have guineas but I don't know if they can ever be tamed. Mine are wild although I still trim their feathers from time to time to prevent flight. Once they fly, they can be stolen so I don't take chances. Noisy screechy birds though.
I have a wood burning kitchen stove and parlor stove I cook on and we have all learned to judge temp by feel.I remember hearing a story of a woman who did the same thing. She'd hatch eggs for her neighbors. She'd gauge the temperature and placement of her basket by placing her bare foot on the hearth in front of the stove.
In Egypt, they had huge walk in incubators. They would hatch hundreds of eggs at a time. The workers were trained to know if the temperature was right by how the temperature would feel to them as they walked into the bators to tend the eggs.
It's been a experience,but well worth it!
