Denver Broncos superstar Von Miller is an expert when it comes to chicks ... 'cause the Pro Bowler tells TMZ Sports he runs his own POULTRY FARM back in Texas ... and loves it!
The Dallas-born linebacker was at an ESPYs party at Lure in L.A. last night -- rockin' a cowboy hat -- when he raved about all things Texas ... the fashion, the music, the square-dancing and the farming.
Specifically, Von talked about the chicken farm he built at his Dallas home last year.
He started with 38 chickens ... and now, he's got 43 ... telling us it's not just a hobby -- it's functional because he eats the birds and the eggs.
Miller has previously said he wants to grow the farm into "something bigger." Sounds like he's off to a good start.
