So i have hatched around 30 quail chicks who have now reached the ripe young age of 5 weeks ! When would be a good time to start sexing them and grouping them up in breeder pens ? So far i have 3-4 males crowing but apart from that i haven't noticed any fighting or other breeding behaviour apart from during a feeding frenzy when they occasionally peck at each other to get to the front of the feeder.
