This is my first guinea incubation and hatch. My eggs are at day 21-23 what are folks referring to by "Lock Down"?? and pipping? I have raised the humidity up to about 80 % the digital temp and humidity is not accurate and I have regulated the tempature with a regular glass themomtor that came with the incubator. I raised the humidity because it looks like some of the eggs might be starting to hatch. Several eggs I collected were sat on by the chicken hens and we had a huge heat wave in California during the same time that could have started the incubation process prior to my putting the eggs in the incubator. I can see several eggs with tiny shell fractures and doing my best at candling with a flash light can see several with slanted air pockets at the top of the eggs. I also have 3 duck eggs hatching with these and all 3 of those eggs have slanted air pockets for sure. There is one egg that has some liquid dots forming on the top of the egg that are coming out of the egg and I can see tiny fractures down the sides of the egg as I sat and watched the egg for a while the liquid had tiny bubbles that appeard like something inside was causing pressure that was forcing the dots of liquid out of the shell. Any ideas??
