My chicks are 5 weeks old now, (here's another post about them https://www.backyardchickens.com/forum/viewtopic.php?id=369050 ) And I was wondering if I could give them some scratch? Are they too young to have it? What are some good treats for chicks? I've tried crickets and mealworms, which they LOVE. But I also tried yogurt and lettuce, which they hated! What do your chicks like? Also, when can I switch them over to regular grit? Currently I'm using play sand, and it doesn't seem to do the trick anymore... oh yeah, and when do "chicks" turn into "pullets"?
