A number of years ago I got some Yokohama and Phoenix chicks as I've wanted long tail chickens for many years. I was very disappointed in the chicks as they were weak and frail. I did manage to raise a few of these chicks, but most died within a few weeks. When the few that lived matured I decided to try some crosses with serama bantam and white crested black Polish. From this cross I picked the most promising roosters to pair back to the pure stock. I've repeated this process three times and yesterday my fourth generation chicks hatched. The cross has produced very healthy active chicks and some unique colors. Below is my third generation rooster whos tail is sill growing. Of course, I'm wondering about the tail length of the new fourth generation. Am I wrong in believing the all cockerels will have long tails when mature??
