I have 5 birds in two groups. Three are right out the back door (until spring ) and the other 2 are in the larger fenced area of the back yard. Well, I can't let my little mini Beagle/ Dachshund outside alone anymore. They all chase her and try to beat her up. She only weighs 12 lbs. and I think they might really hurt her. The dinosaurs are about to discover bird jail.
