Young starling

Newby here so hope this is the right place to post. For the last week i have had a young starling wondering about in the garden. It seems healthy enough and feeding well on the mealworms i have put down for it but it doesn't appear to be able to fly. I cannot see any evidence of any damage to wings. i do get a lot of starlings in the garden and none of them have shown any interest in the young one. At what stage do Starlings normally fly and should i be concerned?

Tried to get a photo but it keeps hoping into the undergrowth when i approach.
