Nope, they don't need grit for yogurt. I always begin to offer it when I give yogurt, which is the first treat I give young ones, just because it's easy to do and grit is inexpensive, and it doens't hurt them to have it. But it's absolutely NOT necessary. Enjoy your babies! THey grow SO fast!
OMG you're are not kidding. I feed them in the morning and leave to start the laundry. I come back about an hour later and I swear they are bigger.
Gotta love'em. I've heard of mixing some grit into the yogurt. Sounds like a good way to get them started. I'm really waiting to be able to give them a worm. I've heard here so much about how funny that is. They are 15 days today. I think I'll wait till the weekend for the worm olympics.
I have 3 age ranges of chicks...4 wk olds, 3 wk olds, and 2 wk olds. I have given them all yogurt, and have taken them outside to play already. They all LOVE grass and bugs and such. From my comets to my bantys. I make sure they have grit, though I don't let them have free access to it yet, and they are all healthy, happy and growing like crazy! They love playing outside! By the way, I learned that is the best place to give them yogurt...even a wee lil bit.
I gave my two week old chicks yogurt this morning and the silly things wouldn't eat it. They just ran through it and spread it all over their brooder. Then the others were pecking it off each others feet.
