I have been letting my chickens free range in my backyard the past 3 or 4 weeks. It has been working fine for the most part. I have an elderly neighbor on one side who has gotten interested in the chickens. He asks a lot of questions and I would see him standing in his backdoor watching them. A couple of weeks ago he asked if he could throw some bread crumbs over the fence to them and I was envisioning some leftover toast or end pieces of stale bread. I said nothing with mold, no citrus, garlic, onions, etc. A few days later the chickens went running over to the fence when I let them out and started pecking the ground there. Yesterday when I got home one of my hens was on his side of the fence. So glad I found her before his two dogs did! So I went and retrieved her and when I did I saw that he had a 50 lb back of poultry feed standing in the grass, just with the top folded down. I am concerned about keeping this outside for numerous reasons. Is there any reason I should be concerned about him giving them actual feed? I am still feeding them start and grow, but they haven't been eating as much. They get stuff out of the yard and I bring them fruit, veggie and bread scraps. They are about 14 weeks old now. I am so glad that my neighbor likes my chickens. I don't want to alienate him. Should I say anything to him aside from talking to him about not keeping the feed outside?
