My chicks are 5 weeks old and I'm starting to think ahead for the next bag of feed. A friend starts her chickens on layer feed at 8 weeks. I'm not sure I can get grower feed, so when is the best time to switch over to layer? Or is grower too important to skip???? I wanted to go organic and was going to try the Green Mountain, but now I'm seeing lots of posts about the organic not being nutrionally as good. My non-organic option is Poulin, which is half the price for a 50# bag. With only 3 hens the price difference is not a huge issue, but hard not to take notice. I don't feel like I know enough about the different ingredients to make an informed choice. I just want my hens to be healthy and happy and to enjoy eating their eggs! Can somebody help???
