Very sad day today. Had the same thing happen with chick no. 3!
This time the chick was still completely inside the shell, it never broke through. In all three cases the surrounding shell was crushed. Hmm....it just doesn't seem like a normal hatch to me (not that I would know what a normal hatch looked like LOL cause this is my very first time - but looking at various photos on this forum these 'hatched eggs' don't look the same). None of these 3 eggs had a 'zipped' look to them. In all 3 eggs there was unabsorbed egg yolk. This last one, I couldn't see a head - think it must have been tucked underneath. All three were fully feathered. Today is day 22.
So now we're down from 8 to only 5 eggs left. I'm seriously wondering if Mama is doing something to these hatching eggs! She's still very determined to sit on her eggs. Sometimes I could swear she seems to be talking to them. Occasionally she lifts up and seems to be looking at them like someone just moved in there. I dunno!! Wishful thinking on my part??
I took a photo of this latest egg. I'm gonna try to download it here so others can maybe help me with an eggtopsy. I really want the rest to hatch ok!!!
