Dogfish-

I used to have a couple dozen quail yrs ago. I built a chicken coop like shelter for them with a few cone enterences so they could get back inside the coop but can't get out(kinda like a shrimp pot tunnel). I would release them in my field and then let my pointer point them and such then they would find there way back to the coop where the food and water were. Always leave a few in the coop to attract the ones that were released. Worked great! Just an idea. I don't know what your intended use is??
