My girls are almost 5 weeks old (3 BR and 3 RIR) and have been in their coop/run and free ranging for a few days now. They have scratched up several small earthworms on their own and run around with them like the do with superworms but don't eat them. I have also tried yogurt and some fruit and garden greens and they peck at it a little and leave it. It has been a couple weeks since I offered either. Has anyone noticed that they take interest in some things as they get older? Should I keep offering these items. I really want them to have treats but I also want them to get used to things that may help them in case of a problem (i.e. the yogurt for gut issues). I would really appreciate feedback on this. Thanks!
