After candling, 9 "good" eggs went into lock down last Tuesday. Temperature on the Brinsea had remained steady throughout hatching and I followed instructions to the letter for humidity. On Thursday, day 20, the first hatched. Since then I've had 5 more hatch. Today is day 23. 3 eggs left in the incubator with no signs of pipping although at lock down there was lots of movement inside the egg. How long should I wait before I give up and toss the last three? I'm a little sad for them, but am very happy about my 6 healthy, fluffy, curious chicks in the brooder.
