The dog has been scolded for foraging free hand spread grain. Doesn't stop her. She tips over the metal containers and eats the spill on the ground. ( Darn dog! We do feed her!) Our chickens just have a coop w/free access to an acre fenced in for our dogs which is allowed to grow naturally. Old farm land with very rich soil. Everything is A-OK except the food thing. I hate shutting the coop doors especially now as the weather is getting foul here in Maine. I leave grain in a metal bowl in the coop as well as water. QUESTION: Can chickens feed from a tube shape bird feeder???? The long plastic type that you hang?? Thank for any input! Labs are like chickens! They have stainless steel stomachs and eat anything and EVERYTHING!!
