I got some hatching eggs once, and a few hatched, but my heat lamp died one evening while we were gone and I lost all except one! So i ended up selling her. I miss them.
You know about the lethal gene with them? The short-legged creeper gene.
My little Japanese bantam hen began laying about 18/20 weeks. She was also broody a LOT. -finally got a day old chick and placed underneath her. -was the best little mama hen! I wouldn't say she was a great layer due to her tendency to want to stay on the nest. When she wasn't broody, though, she would lay about 4 eggs per week.
