I have 3 hens living the high life in a moderate sized backyard with a nice coop and house. Inside the coop are a waterer and feeder. We now purchase layer crumble for them - as they didn't like pellets. I generally toss a handful of scratch in daily. Two are game banties - very very small, and the third is a big golden comet. All love eating worms, bugs, and free range in the yard most of each day. We do offer some kitchen scraps, but not alot and not regularly. Problem is they basically ignore the crumble. Any ideas for something we could add to the crumble to entice them to eat it? I figure they need the calcium, etc. Thanks for your help!
