The sex-link are my go-to recommendation especially for newbies and those wanting to sell chicks!!!! There’s a good probability that a % of them will make weight as jumbos and it’s a great way to get your feet wet so to speak with quail!!!! If you do choose to keep some past 5 weeks for whatever purpose, I encourage to practice vent sexing then and even earlier because you already know the sex based on color!!!!I haven't actually won in the auctions so I bought some from Zach! lol I initially went with jumbo wild, but when I saw the autosexing asked if I could do some of those instead. Too many gorgeous birds I feel like I can't make up my mind!!!
