He's trying so hard, but he's really having a hard time getting out of his shell. I can sympathize with the poor little bugger... goodness knows, I have a hard time cracking these shells myself when I cook with them! Guinea shells are the toughest shells I've ever known!
He's not a quitter, I'll give him that. He's been working on that hard shell since Tuesday afternoon. I can still hear him peeping away this morning. If only those two cracks (horizontal and vertical) would give way for him! My guinea book says they can take up to 2 days to hatch, so he's approaching that timeframe this afternoon.
I've got my fingers crossed for him!!
