I bought a 25% chick starter feed aimed specifically at heritage breeds for my chicks. I like it because it's all local, non-gmo grains and it's a good price. It also uses whole food sources of vitamins and minerals instead of synthetic ones and the lower protein formulas are soy free. I read on an American Heritage chickens club site they recommended high protein for heritage chicks. The sheet I got with the feed says to feed to laying age, but when I mentioned it on here a few people questioned whether it was actually meant as a chicken feed (it is), and I double checked and realized the label on the bag says to feed just to 5 weeks then switch to the next one which is 19%. Not sure if I should follow the label or the info sheet, but i went with the label and have had my older chicks on that one for a while but left the younger chicks (3-4.5 weeks old) on the 25% starter. Question is, I am going to run out of starter, probably tomorrow. I bought another bag of starter already, but now wonder if I should have gone with the 19%. How long will 44 pounds of food last 15 chicks? Will the high protein hurt them if I'm still feeding it in 3 or 4 weeks? The three week old ones are Silkies and are so tiny, I feel like they could use the boost. I would rather not return the food, the feed store isn't that convenient, but if high protein is detrimental in some way I will.
