I allow my chickens to roam an area in my yard (closest to the house) when I can watch them. Yesterday, one of my pullets found the cat food. It's hidden in a dog house on the deck. Soon, they were all into it. I took it from them and put it up on the table. Within minutes, they had found a way to get on top the table and pirate more food. I moved the cat food in the barn and they followed me and entered the barn through the cat door. So this morning, I put the cat food up before I let them out of their coop. They are searching everywhere for the cat food. I'm getting some very disapproving clucks and squawks. They look like addicts frantically searching high and low. I have given them some grapes to distract them but they immediately went back on the search and destroy mission to find the cat food. I feed Nutrena Starter/Grower. I haven't had an egg yet. They have access to grit. They eat bugs and other findings every morning for a few hours as well as every evening for a few hours. I take them a few scraps (pieces of vegetables or a grape) to watch them play keep away. Are they missing anything or is there any particular reason they want the cat food-other than I won't let them have it?
