Hi! I had 5 of 6 incubator chicken eggs pip and hatch within 24 hrs on 'hatch day', which was this Friday. The chick inside peeped this morning but isn't pipping externally.
What's the latest you had a 'last egg' pip and then hatch, or be alive and then die without pipping or without hatching?
long story short...I had a broody hen couldn't find cheap eggs so when I did the hen had been on the nest for 20 days already. when I got the hens eggs she sat on them for 10 or so days then gave up. she was in a nesting box covered in wire and through her attempt to get off the nest she broke...
