I had 4 coturnix plus one cock, and they layed pretty regularly. My guess is you should probably have around 10 quail. If each one lays an egg per day, minus one day of the week for 6 days (I always give them a day off), then you would get 2 chicken eggs per day (at 5 quail eggs per chicken egg), and one dozen eggs a week. If you want to use them for the same purposes as chicken eggs, be aware that there is a higher percentage of yolk to egg than a chicken egg would provide.
