Yeah, it's pretty cool! I was surprised by the early age of leghorns. I knew they mature quickly as breeds go but didn't expect them to lay so soon. My black sex links and barred rocks went 28 weeks before we were able to plate an egg! I'll try mixing the feed. I'm trying to avoid buying another 50#s of grower feed if I don't have to. Aside from the size of the pellet, the only significant difference that I can see bewtween the two feeds is that the layer pellet has considerably more protein and calcium. What would be the downside of feeding the 13 week pullets the layer pellet?
Thanks for everyone's help!
