Lonely Starling

On the 15th of April I started to pay attention to some Starlings in my roof, they were bringing worms and I heard the chicks.
A week a go, I saw more starlings in my roof but not chicks, they looked more like adults, maybe a colony. 
Now there’s no chick sound anymore (Maybe they learn how to fly) and I do see more starlings around the roof but I’m concern about one. He/she is being alone and singing for the past 3, or 4 days. I feed it everyday but somehow it looks sad, idk, i just feel terrible for it, does anyone knows what’s happening to it? 

  • I'm not an expert, but that looks like one of the chicks that our starlings produced. They would stand near the nest calling out to its parents. The parents would come.back and feed them. Yesterday afternoon the chicks started flying by themselves and now feed together (parents still putting food in chicks beaks, but the chicks are now standing next to parents on the feeder itself). Hopefully yours will soon find its legs too.
