My chicks range from 5 to 4 weeks old and the two chick feeders I had out were just not enough to last through the day while I am at work. I started using a 12# hanging feeder yesterday and it seems to be working fine, so far. I plan to keep the feed available 24/7. I am presently not allowing them to range in my back yard, mainly because I do not want them getting into my neighbor's yard, but plan to when they are grown and laying. By then, they should be big enough to keep them below my 4' fence. It will be interesting to see how much difference that makes in their feed intake.
