Barn owl chicks? (1 Viewer)

Hi
I have had a pair of barn owls taking residence in the end of our barn for a long time which I have noticed cough up pellets regularly. Recently though I have started to see pellets on the floor which have white feathers stuck to them. Thinking that there may be chicks inside I decided to fly my drone up to the hole to take a look and I could see a what looked to be a fluffy owl in the corner of the screen. Could the Owls have had chicks and are the fluffy pellets from the owl chicks?
Many thanks

could well be,if one of the chicks dies the adults will feed it to the remaining chicks
