Hello, I am still a new bee, but my hen went broody and hatched some eggs. But she stayed on nest. From what I've read here, some have dismissed eggs past 21 days as duds....well she kept sitting, so I let her....she ended up hatching eggs (which I was absolutely positive of the dates) around 28-30 days. They are normal healthy young'ins. So, if she was on and off the nest, (she would get off the nest to go to the bathroom and stretch, I had her food and water right there with her, why would it take so long to hatch?? I did notice that the egg & membrane was dry (I just learned that I could/should have wrapped them with a damp paper towel) and towards the end they needed help getting out of shell. But they did survive.
Should I let eggs go past 21 days?
If so, do they become mentally or developmentally delayed?
(I do have one Ameraucana that seems slow)
Also, a side question, is there any way to hatch eggs (either with a hen or incubator) that would help you have more hens than roos?
(I saw something on net, but not sure if it is a hoax)
Thank you for your kind help....
