Well, I've never had that problem and most of my flock will eat yogurt & garlic off a spoon. However, you have to remember they are still learning what food looks like. Yogurt doesn't look like crumbles, but after a while they will probably nibble at it. Because chickens nibble at everything.
Here's are some suggestions.
Try putting the yogurt in with the chicks for a while a couple times each day. Eventually someone will try it. Once one bird starts eating it, the others will join in.
Or you could try to sprinkle some of their starter feed on top of the yogurt.
Gently hold a chick in one hand. Pet it for a while. Whisper sweet nothings to it. Make sure it is calm. Hold a teaspoon with yogurt your other hand. Dip the tip of the chick's beak into the yogurt. After this bird starts eating the yogurt, return it and the yogurt to the brooder. Once the others see one eating, they'll join in.
We feed certified organic layer mash to our hens. Unlike crumbles or pellets, mash is very powdery. We mix a small amount of yogurt with the mash to make crumbles. We do this twice a day. We keep water, feed, grit and oyster shell available to our flock 24/7 free-choice.
Make sure you use a plain yogurt with active cultures. Mine like it best with crushed garlic in it.
We saved the plastic trays from take-away Chinese food to use as treat dishes for our flock. They can be cleaned easily with boiling water and a little soap after each use.
Always remove any uneaten yogurt after 10 minutes and clean the dish.
