I thought I'd give my 6-week old chicks a real treat and bought them black oil sunflower seeds. I had read on here that BOSS is a commonly given treat, but my chicks just stare at the seeds, pick at them a bit, and leave them. Is it possible that they just can't get through the shell yet? When are chickens ready for this treat? Any experience? If they aren't going to eat them, I am going to have to find something to do with this 40-lb bag of sunflower seeds!
