Every evening for the last couple of weeks I have had the opportunity to spy upon two young owls positioned on old crags. Owl to East is a juvenile Barred Owl and owl to southwest is a juvenile (likely male) Great-horned Owl. I do not know if they can see each because our house may be breaking their line of sight. Barred Owl appears to be monitoring an area dominated by cut fescue while Great-horned Owl is over a mixed meadow with a few large trees and pond. Barred Owl has been an issue but Great-Horned I suspect is harassing free-range birds in cockyard. Even hens are roosting in tall grass on the ground sometimes with juveniles that are not their. Owl has been coming in at night going after birds roosting up causing a stir resulting in dogs then running owl off. Owl being juvenile may be reason it is so persistent and possibly not putting any more effort forth other than that needed to flush chickens. Adult owl would not waste its time especially with dogs about.
 
Try closing your birds in a well built coop each evening and let them out in the morning. It's nice to not even have to consider a predator after dark.

You should read some of centrarchids threads.

He is not your typical BYCer, has a unique setup and management technique set up, looks at it all from another perspective, he's written a lot about it here.

Is fascinating reading, IMO, I've learned a lot from the documentation of his observations.
 
GHO came back again tonight. Moon full. I was late to pen a hen up so she roosted on her pen. Owl (juvenile this time) had that hen cackling for a good 60 seconds before dogs got there. Owl then flew off to south and dogs gave chase. Owl was very easy to see because moonlight so bright. Owl appears to have been standing on pen next to hen that was fully exposed. Hen and several other birds were fluffed like they only do when owl visits. Hen had a small feather in her beak when I got there. It looks as if she make have tried to defend her self by pecking at owl. If owl operating true to form, then it would have been trying to drive hen to ground where it would grapple her there for kill. Hen seemed on inclined to cooperate with that. Her juvenile offspring of 9 weeks was in pen and all worked up even aggressive at his mother when I put her in pen. He also made a aggressive sound interspersed with the "do not touch me" trill.
 
I sat out for 90 minutes with a camera. Darn Lucy hid in high weeds behind me and rushed out as owl flew in causing owl to make an abrupt 120 degree turn. Dog responded to low pitched warning trill as birds produced as bird approached. Owl did not come back after a further 60 minutes of waiting.

Something to note. Juvenile owl flies straight in to land on pens. Adult always approached by landing in taller tree nearby first. Mosquitos tried to carry me away. Sweet white grapes helped keep the pain at bay.
 
Barred Owl now coming in and landing directly on pens leaving tracks in snow of pen roofs.. Such owl general not a threat to chickens, adults at least, but the chickens get stirred up nonetheless. They do their classic anti-owl display and make a ruckus. Barred Owl is going after the very abundant mice on the ground that became evident once I moved pens about 100' into a new row. The mice can be seen even during daylight. Rodent abundance I think might qualify as being at plague levels. With all this prey I am going to have a lot more predators testing my defenses. For some reason the rodent abundance has always been high in the areas thick with Cheat Grass and has become more so with ground predator exclusion and the addition of grain to the menu.
