I have some chicks that I'm raising on organic feed from day three. They seem to be growing at a slower rate than the first group I had last year that were on commercial feed (I got the first group at 6 weeks, and couldn't find organic feed for the first two months I had them, so they were basically raised on commercial feed.) My question is has anyone else raised chicks on organic feed and noticed a slower growth rate as compared to those raised on commercial feed? I'm thinking it may be due to the things that are added to commercial feed and not found in organic, such as growth enhancers/hormones/medications etc. Or perhaps the fact that it's winter and the chicks are still inside in a large brooder and not outside getting sunshine right now is contributing to the difference in growth rate? Any thoughts or past experiences/observations? Thanks in advance for your comments!
