My bantam cochins are about a year and a half old. I feed them a layer feed with an occasional leftover from the kitchen. My neighbors had some whole corn that they gave me and I am wanting to give it to the chickens. I'm nervous about giving it to them because I am afraid the kernels are too large. The chickens are fairly small. I also have never gave them any grit. Their run is covered in several inches of fill sand so I never bothered to give them any actual granite grit. I am hoping to hear some advice from someone before I give it to them. I have never even given them cracked corn, maybe they won't even like it.
