Behaviour of an elderly African lovebird
My female lovebird is now 11 years old. She has entered a continuous cycle of trying (unsuccessfully) to lay eggs... followed by a period of plucking her chest feathers. When her chest is bare she stops, the feathers grow in and she is calm for a short while. Then the egg-laying behaviour begins again. By this, I mean she sits on the bottom of her cage and if I take her out, all she wants to do is shred paper and rush back to the cage.
When she is in this mode, her droppings are large and loose. But I believe she has lost the ability to lay eggs due to her age. She seems psychologically messed up, but she has had a good life with lots of love and attention.
Is there anything I can do to help her get over this futile cycle? It can't be good for her health. Can you estimate how long she is likely to live if she keeps this up?
Thanks in advance.
