I've read on here that you don't start feeding them layer feed until they start laying eggs, and then I didn't listen. My girls are 14 weeks old and they were almost out of their chick starter/grower. I didn't really want to buy another bag of chick starter not knowing how long they would take to start laying eggs. (they are hatchery SLWs). The 50 lb bags of feed are a lot more cost efficient so instead of buying who knows how many small bags of chick starter/grower I bought a 50 lb bag of Layer Pellets (17% protein). Now I'm worried that I'm going to cause a blockage or something because I'm giving them the wrong food? Is it really so bad to start the layer pellets now? Should I just go buy more feed? What's the harm in too much calcium? p.s. I'm not trying to be a smart-alec, I really am wondering.
