One the girls from my first batch -- which were ISA Browns -- Su, disappeared somewhere the other night and hasn't come back. I'm betting that whatever nabbed the guineas also nabbed her.
Other than the losses, the flock has been doing great. Eclipse has been practicing his foghorn crow, while Simnel has been practicing his squeaky toy crow.
Baba Yaga and Frau Pfefferkuchenhaus, the two chicks who Marshmallow hatched at the beginning of the month, are growing nicely, and have the most beautiful feathers coming in....
So, things are going good.
Sorry about your hen, and I hope that you can deal with the mites quickly.
