Advice on baby ringneck dove please

[SharenYorkshire]

Hello, im in Yorkshire, England, 3 days ago there was a baby dove on my doorstep, i ushered it away to a safe place near my sleepers, 8 hours later it was still there and the mum hadnt returned to the nest (built on my satellite dish) and still hasnt returned up until now, i lined an unused rabbit hutch with paper scattered some wild bird seed and a small dish of water but it hasnt touched it, i rang a wildlife centre Nr London 290miles away) and i was told to try and feed it some baby cerial mixed with water of which i have got about 10ml down at most they also told me to use some suet, wet dog food and seed made into to pellets and try to get that down which i havent managed yet.
Is this advice correct? How much and how often should she be fed? Will she be ok outside in the hutch its snowing here at the min? How old will she be? She is about the size of my hand bodily feathered and has tail feathers about a third way up.
So far ive been unsuccessful in getting her to eat properly or drink at all ive been putting drops just into the inside of her beak but she doesnt seem to be taking it. The products named on this site for feeding dont seem to exsist here and the wildlife centres really dont seem interested in helping as doves and pigeons are thought of as a major nuisance here

Any advice would be greatly appreciated, please remember i am in rural Yorkshire and not alot of products are available here.
