I've never had a young bird get broody. 7 months! My man and I were surprised and we've had it! Its hot here and birds aren't laying as often anyway. Customers need eggs. We don't mind an older broody bird but this odd bird just started laying a nice large egg every day. She was a strange developing bird, larger, just now developing tail and comb. Hogging a favorite box too. BOs are prone to broodiness but this is too much. Wacky hormones? She's on the 4th day and is going into our isolation hutch now.
