What age are your chickens and what do you feed them? If you feed a commercial feed is it crumbles or pellets? Ours are 9 weeks old now and eat a crumble grower food. They make a huge mess even with PVC pipe feeders and the crumbles get stuck in it. We have to bang on it to get it to fall. Any suggestions? Do you make your own food? We are currently feeding this brand, grower, which is a fine crumble. No scratch added to the food. http://www.originalfeeds.com/ Thank you!
