I am so happy to report that our wee hen Nudge has recovered from her injury. This morning, we found her first egg in her temporary sleeping quarters!
Hens typically won't lay if their bodies are distracted with other things, so an egg from Nudge means she's healed and happy. So today my lovely husband and I partitioned the run to help Nudge reintegrate with the flock. As you can see, the 'Welcome Wagon' are none too thrilled to be cut off from pecking the new addition. They keep throwing themselves at the fence.
I do think chickens are wonderful, but they're not the brightest creatures I've ever encountered.
