Is that early or late? This is my first Brahma flock, so I have no idea how long it will be before anybody lays. I'm assuming next March, since winter is almost here, but I could be waaayy wrong. My mixed flock started laying in November when they were about 6 months old.I wouldn't worry too much about the hocks yet. The feathers appear soft and pliable. Real vulture hocks are more like wing primaries.
One of my Partridge Brahma pullets laid her first egg today, at 25 weeks and 5 days. I think that may be a world record for LF Brahma.
