This healthy looking young one was lucky as its guardian did a lot of research before taking on the role as mother.
It was given water with its food until it learned how to drink. It has insectivore supplement added to its mince.
The chicks get water in the food the adults give them such as worms which have little nutrient. I don’t think an eye dropper is a safe thing to use.
I suggested getting some meal worms from the fishing supply shop to teach it how to find its own food. Perhaps when it is hungry and demanding it should be taken into the garden and taught how to hunt. Magpie mothers use food and hunger as a teaching aid.
It has a cage which it puts itself in at night for safety but spends all day roaming free.
