I'm bringing home two week old chicks tomorrow. I already have three laying hens who had begun laying before I expected them to so I have almost a full bag of grower/finisher feed left from having to switch my hens over to layer. Wasn't sure it was safe though. Didn't want to waste almost a 50 pound bag of feed if I didn't need to. Any advise or should I just go buy chick starter like I did with my first group of chicks?
