I'm sorry to hear all this. But the fact remains that you cannot change another person or make your aunt assume responsibility for anything she does not choose to be responsible for. You, however, sound like a very caring and responsible individual. So I would encourage you to do all that you can to do what's best for all the birds on the property, regardless of who owns them. Maybe you could integrate the flocks and make them all one? That way you wouldn't be frustrated with her not taking care of "her" birds. Do it for your uncle - and for the chickens.My uncle had stage 4 lung cancer she never really took care of him I took care of him for the 10 months that he had left in his life. I made him meals spent all my time with him she did nothing, she would rather go shopping than to stay at home with him. So I would take care of him and all the chickens. Before he got sick me and him would take care of the chickens together my aunt did nothing with the chickens even when he was alive. I live in an apartment so I dont think the landlord would let me have them on the property. When my uncle was dying he asked me to keep taking care of the chickens until they all died. right now they are alive and happy, she just doesnt want to responsible for them anymore
