I've raised £350 to Build a corvid rehabilitation aviary

Please help me buy an aviary to help rehabilitate and house injured corvids(crows, jackdaws, rooks, magpies).
Thanks to previous generous donations I have an aviary for the pigeons and other seed eating birds.
Josh the Jackdaw needs this special home. Poor Josh was found with a badly broken wing. Unfortunately he's never going to fly properly again. But he can still live a long and happy life in an aviary.
Pauly the crow is also recovering from a broken wing. He was found a mile and a half up the road from me, close to the main road. He's still healing and it will take time before we know if he's going to be releasable or need the aviary as his permanent home. In about a month he will need the larger space of an aviary to safely stretch his wings and see how his flying is affected.
It all started last June when I found a young crow with Calcium deficiency. Crows suffer with this condition, also known as white wing. It makes their feathers weak and means they can't properly fly until they grow stronger feathers. They need a good diet to do this. It can take up to two years. I had Wilbur for three weeks before passing him onto Jenny at Haven Watch who had other young crows with this same condition and a big aviary for them to live in till they regrew good feathers.
Since Wilbur I became part of Merseyside bird rescue group and have learnt bird first aid and how to assess birds for treatment, what medicine to give and when to take them to the vet for extra care. I have always rescued animals, since I was a young child growing up in rural Ireland, helping everything from shrews to horses. I feel like I was put on this earth to help animals.
Any extra money raised will go towards the birds food, medication, transporting, vets bills and anything else the birds need.
