Great! I just prefer to wait after having crop issues in a Cochin chick once. Might just have been coincidence, but I prefer to wait a bit.I have live as well as dried mealworms. I feed my mealworms chicken pellet feed & also have the mealworms dusted with chicken feed, this is known as loading & many people that have reptiles will roll worms in nutrition dust to get the nutrients into the reptile. My chicks went nuts for the smaller live worms & I offered them at 3 days old. Just a few at 1st...abt 3 worms per chick. It teaches them foraging skills & also they looked forward to my visit. Chick crumble feed is available at all times, but a few live mealwoms once day is not a bad thing. I had 3 runt chicks, not doing as well, so I'd take them out & give them 10 mealworms each, it took them much longer to catch & eat & other chicks would knock them over & steal their worm, so taking them out for a few min helped. After a week they were little experts & zipping around, able to compete with the rest. I offer treats only once or twice a week now, but when they were chicks, eating every 15 min & growing fast, a few mealworms once a day wasn't bad for them, they still ate a ton of the nutritious chick feed constantly. The 3 runts caught up & are doing great.
