A word of caution- I too am new to chickens, and read on here how much they would love yogurt. I had some strawberry yogurt that the kids decided they "didn't like" (i.e. wanted it at the grocery store, but changed their minds later) and gave it to the hens. They loved it !
The problem - Spot, a Houdan, apparently turned her head to the side to eat it, basically laying her head in the dish, which covered her top feathers with yogurt. (I was at work). The next day, I could not believe how she looked. Her head feathers were covered with other birds feathers, dirt, and shavings, all stuck to the now dried yogurt mess.
So after consulting this site and hoping the yogurt mess it would work out on its own (it did not), we got some baby shampoo, brought her into the kitchen, and gave her a salon treatment ! Let's say that shampooing a chicken is not my forte, but we all survived and she looked 100 % better without all that stuff stuck to the top of her head.
So - yes they loved the yogurt. but keep an eye on any birds with top hats !
