I am new to raising quail. in fact im just now building a pen. but i need help. i am building a 4ft x 10ft x3ft tall pen to keep about 20 or so bob whites in. i will then take two plastic totes and cut aut the tops and put wire on them. and of course have a heat lamp on top. i have two so i can clean one and trasfer them. but my ?? is how big of a tote do i need for how many chicks and also one they are of age to leave the brood tote can i put them with the older birds in the 4x10 pen. (that is assuming i dont eat or sale them) just saying what if i had a few left.
