Back to you foodchain, on Japanese Quail & Chukar. Your knowledge seems to be far greater than what I'm getting on another Forum.

I have a large multi level pen 7' X 12' @ 6' tall in my back yard, sits on the ground under a large tree.

I have hatched over 60 Japanese Quail over the year that I've had them, each hen would lay an egg per day. After hatching out 27 chicks I sold off all of my males to save on feed, knowing that I would have plenty breeding males in 6 weeks.

Shortly after doing so the egg production started dropping, down from 16 - 18 eggs per day to 1 egg per day. Do hens need a male in order to produce eggs?

As for my Churkar at what age should the be full grown and laying eggs?
