Just went out and checked on progress (it's SOOOO hard to be patient! ahh!!). All the Buff Orpington's eggs are same as this morning, but Lena's other egg (one of the calicos) just pipped!!When I was convincing my Cochin hen Lena to go broody (I wanted her to have some of the shipped eggs, partly so that I wouldn't have so many chicks under one hen, and partly because Lena has hatched before and I know she is a good mother), I gave her one of her own eggs to sit on. Cochin that she is, she was broody by that night! Since it was only a few days before the shipped Calico eggs arrived, I decided to leave Lena's egg with her. On Friday, it hatched!!
Today, one of the Calico eggs pipped! I can hear cheeping inside some of the other eggs as well! This is day 20 for them, and hopefully I'll have chicks tonight or tomorrow!
