I would not recommend you buy any pets from the Souk. I bought 2 birds and after a while they both died one day! ONe of them always had somekind of skin/fether condition.
I gave them medication mixed with food but still they died! Also, I bought a plant for my fish and it infected them with some cist and half my fish tank died.. I'm still giving medication to the fis
I know a lady who rescued some cats from the Vets, cause they were bought at the souk and had ringworms which invected a family who put them in the Vet and left them.
Right now, i've heard a lot of bad things about the souk animals.
They are not treating the animals well, the animals are very sick and they don't tell You.
I would suggest you look at the QAWS or other options for getting a healthy bird.
Good luck!
