How do owls do that?

While we are on the subject of owls, I read that Hagrid sends Harry a 
message via Hedwig, telling him that the Dragon egg had hatched. SS 
Considering where the owlery is ... would it not have been easier to 
just tell Harry in person, than to go fetch an owl? (I am not sure 
where the owlery is located in regards to Hagrid's Hut)

Also, when Hagrid & Harry were on the island, with the Dursleys, 
Hagrid reached into his coat pockets and used an owl to send a 
message to Dumbledore. Why didn't he use that owl again, rather than 
use Hedwig? Does Hagrid have his own owl? Or does he just borrow one 
from the school?
