I have four australop hens, and over the winter three of the four stopped laying. Since spring, two of the three have started up again. However one has not layed since last fall. If anyone has any advice or ideas on why that would be appreciated. I just recently gave a broody hen some of my duck eggs to hatch, but the one hatchling has integrated well and she wasn't laying before that either, so I don't know how stress would be a problem. Recently she's been bullying more, it started with the lowest in the pecking order, but she has been picking on the others too. Today I separated her when I saw blood on another hen. My best guess would be weight, she seems the fattest of the group, so if anyone has diet ideas that would help too.
