I feel blessed reading all this. I don't fly my birds except in the very large aviary that they live in. I love walking in there while they are flying around me. It is about 50 by 13 feet and covered entirely with heavy knotted aviary cloth. The fence has a light weight aviary net/ bird netting on it. So the entire area is secure and the aviary out front is 4 x 4 x 6 and I have found hawks sitting on top of it. But they can lick their chops and not touch either my chickens or my pigeons, lol.
I did that all after hawks came down and killed some of my chickens. My silkies. We live right near a hawks nest and can see them flying over head any day or time. They are multiple around here and I am in the city.
One day I went out to my coop and even with all this netting, there was a hole. Well some how a dumb raccoon got in through the hole, now repaired, but I opened up my huge nest box and there that thing was sleeping in there. Why he didn't kill my chickens is going to be forever a mystery. I shut the coop door and locked him in and my chickens out until my husband came home. He dealt with him after that. I consider that a miracle but a coon could still probably make a way in, but not a hawk. lol.
This picture was taken in the winter. It has changed alot since now I have a huge 10 foot by three foot by five foot tall rabbit cage in there at the end that has three divided cages in it. I put the breeders in those if I want to or leave them open for the birds to go in and eat. That way the chickens can't get their food.
The other photo is my aviary out front that has a roof on it now. This is an old photo.
