I posted this video on the Guinea forum and it got me thinking, what is the oldest egg you have hatched? I found one of my guinea eggs laying in my yard. I brought it in and set it on the kitchen counter. There it sat for three weeks in a house that was 78-80 degrees. My intent had been to find the nest and put the egg in it. But my girls hid their darn nest so well I can't find it. I was putting duck eggs into the incubator and decided to put the guinea egg in also. Low and behold three days early I had a strong keet hatch! That egg was old, never turned while sitting on the counter and kept in way to hot of temperatures. I was shocked to see life at 7 days and even more to see movement at 14 and 21. I managed to get the entire hatch on video!
