We have 4 chicks that are about 10 weeks old. We're going to be starting them on developer feed pretty soon. Over the weekend, we let them hang out in their run (instead of brooder), and they obviously ate a lot of grass/bugs/whatever. As a result, they ate less feed. Now, you'd think this would be obvious... but it isn't. Is it preferable to keep these chicks eating feed formulated to be exactly what they need? Or is letting them out for 8 hours a day okay? I know, i know, before all this they always ate 'naturally'... but that doesn't necessarily make it -better- for them. Any ideas? NOTE -- we still leave feed and water out for them when they were outside, and they did munch some. but they munched on lots of yard, too.
