Please help save Lou Lou the pigeon from Cancer

This is little Lou Lou the pigeon, she is a female and has a large Tumour on one of her legs that is slowly growing and cutting off the blood supply to it. She has been seen by an Avian Vet and had x-rays and tests done to determine if this is a localised cancer which luckily it turned out was the case and there is no evidence of any spread to other parts of her body. The vet has agreed to amputate the leg on the 14/12/23 but the cost of this is going to be around £800. We have over 100 birds in our care at the moment so this is not something that we can afford so we have set up this fund raiser in the hope of raising enough money to try and help her. If we cannot raise enough then we will have no choice but to cancel the appointment and have her euthanized and we really dont want to have to do that as she is a lovely little thing. The initial tests to check if the cancer had spread cost us £262 which we have paid for ourselves but now we need to raise enough to cover the operation as we just cannot afford that. We really want to help and save her she is a sweet and dear little pigeon but we can’t do this without outside help. If you can spare anything no matter how small it would be greatly appreciated. Thank you so much xx
