Make sure you don't over do it since they will get more nutrition from the blended feed. Add some grit if you give them grains or anything hard that needs to be ground to digest. They can eat just about anything but they really like fruits, veggies and bugs.
They're five days old I think I'll pick up some mealworms for them next weekWhen I was a kid I our hens sometimes raised their own chicks and I can remember tiny chicks eating ants and termites as soon as the ventured out of the coop. I am not sure if you mean five days or five weeks. I wait until they are two weeks old but they can eat most any treats as soon as they hatch.
I love watching when the first chick notices and gets hold of that first treat. (Or really anything new, even if it isn't food!) Chicks are very alert to change and to each other so other chicks will ignore the remaining treats and instead chase her all over the brooder to they to get hers away from her. Doing this with live worms is especially fun. But use freeze dried worms or worms for your worm farm as the ones in your back yard soil might carry parasites)
Hand feeding chicks treats (mine love meal worms) will make them "love" you...or at least stop fearing your hand when it's coming into the brooder!
I got mine Saturday when they were 3 days old! I assumed the same thing How many did you get?Definitely, I've been taking pictures almost everyday haha. When did you get yours?? I got mine on Friday (26) and they were two days then so I guess their birthday is Wednesday the 24th
