One of the most important concepts the guy talked about in that last video is where he says that

"they may use fire annually to impact 1/3 of a unit but they will impact 100% with the cattle and how doing this doesn’t confine or put the mother’s and young chicks in a box……It creates a mosaic of different successional stages of plant communities across the landscape that the birds can then pick and choose from"…..

I think about what PCP said in raising young turkeys and how he thinks they need a certain height and type of grass for the first few weeks……Taking that into consideration and the fact that your quail and turkey chicks are probably gonna be hatching out across a matter of weeks and maybe even a couple months…….then having that constant mosaic of plant communities at multiple stages (plant heights) would in my mind offer the best possible habitat situation for optimal survival rates……In other words, you’ve got an optimal stage of plant community growth available to them at all times for whatever stage of growth they may be in from egg to adult . They have lots of options. That is the concept the guy is talking about in the video
