Some guy gave me around 25 quails for free. They are mix of many different breeds. But I was wondering do quails lay eggs in the winter or are they like chickens and don't? Also should I put a nesting box for them to lay or will they just lay on the ground in the cage I have them in? Also, what is the protein min they should be eating? I been giving them Purina Flock Raiser and they love that but it's expansive.. Any other brand I can feed them that's cheaper?
