Thanks, that is a lot of good ideas!
I was going to do sunflowers for the doves, didn't know the deer liked them too.
Last time I got quail, it was adjacent to a soybean field. Their crops were full of soybeans. I think I will add the peas and beans to my mix and see what the upland birds like.
Do some research on T-2 toxins and soybeans before you make that decision. Quail do love beans but they may not be great for your populations.
https://trace.tennessee.edu/cgi/viewcontent.cgi?article=3426&context=utk_gradthesI plant sunflowers every yr. Deer only let them get to the bloom stage once, every year after that they've kept them mowed down to 3 inches.
If you can get millet, milo, Egyptian Wheat, and ragweed to produce enough seed to last into winter I think it's a great option to look at for quail.
