I just saw my first family of Quail chicks this year and they were tiny. They can only be a day or two out of the nest. At work we have a nice garden type common area out our office door and they are living in the bushes just outside my window. They have been getting seriously harassed by a magpie. Mom and dad have been doing their best to defend and are a pretty tuff couple. I wish that I had a pellet gun with me so I could kill that dang magpie. Another week and they will have a much better chance, but that is a long time when you are the size of a walnut.
If I had to guess, and depending on elevation and location in the state, I would say that the chukar should start to hatch in about two weeks. I believe that they usually start their hatch a couple weeks after the quail start theirs.
