hello! i’ve recently moved in temporarily with my grandmother and she has 2 indian ringnecks but they don’t seem very happy, i think their cage not being big enough for them and not having enough toys might have caused it so i wanted to ask, what size and shape cage would be good for two indian ring necks staying in the same cage? and what type of toys would be good to get to stimulate them? is there anything i should know as a first time caretaker? i’ve never owned parrots before this and any help would be appreciated !!
