I replied to your other post as well, but I will also reply to this one as well. In particular something that you mentioned struck me. You mentioned that your parents think its dumb to keep chickens for pets that they are for meat. Something that you can propose to them is that they are serving your family with a purpose aside from just meat. Their eggs. Their eggs are 10x healthier than those that you would buy from a grocery store, and they are packed with amazing flavor, golden yolks, and plenty of protein. Also heres something to consider, and I will be honest, it isn't for everyone. But something that you and your parents can consider is that when your chickens reach that age when they retire from being productive egg layers, you can slaughter them for meat. Now of course no one necessarily wants to eat their pets, but it is something to consider, and making that kind of offer to your parents may be a way to let them consider letting you keep chickens again. At least if that were to be the future case you would know that you raised them well and provided them with a humane and happy life.
