Lol Sylvester that is too cute my girl has a crusty crest as I fed her some yogurt that I found hidden in the back of the fridge.
Thanks for the tip I need them something to think about!
My hens like yogurt too. I get them the plain no-flavors Greek yogurt (I happen to get Trader Joe's 0% fat) because we noticed there's higher grams of protein in Greek yogurt rather than lower grams of protein in ordinary yogurts. The higher fat content yogurt can be used in winter but during summer (which is almost all the time in our climate) we use 0% fat content yogurt.
