I'll definitely post here what she says! I like the how big your area is and the extension sounds good. Grapes can be finicky but give it a shot!If she tells you what they are, I would love to know. I would love something 4-6 ft. tall and about 4' wide (ideally!) A bit wider is okay. Taller is fine, but it means I probably woulddn't be able to put a shade-cloth over the top in warmer season if toomuch taller (use shade cloth both for 'shade', but also to keep hawks out of extended run in the 'warmer'7 ish. mos. of the year. (i.e. now snow part of the year)
When I extend my 'safe run', I will be replacing the current chain-link fence (5' tall) with 8' fencing. With teh compost pile and grapevines INSIDE the run, it will allow me to string electric fencing around the run- 1 strand a couple inches off the ground and 1 strand at the top. I plan on putting chicken wire mesh on the pergola. All of this will mean (with the current pines) nearly all of the 'extended run' will have some sort of 'upper structure'. I realize it won't be 100% hawk-proof, but about 80% will, and all of it will greatly reduce a hawk's ability to see the chickens, and therefore prevent an attack.
I've attached a rough sketch of current + intended run. I have not put in placement of my multiple coops, but the 'secure run' has solid wood & metal roof presently on 10' of the 18' depth, and will have solid roof (hopefully!) with corrugated smokey plastic roofing by next winter. (it filters out some of UV, decreasing temps, but still letting light through. Is/will be, high enough to allow full winter sun in) The entire run to the left of secure run is covered by canopy of the two pines except for bottom left corner...which has a dog pen (with coop in it), including top (6'X12'), so is protected from arial predators. The entire run length along side the secure run has sun shade tarps the length of it starting in April - usually late October. Will still be able to do this with extending the run by 6" by rotating the shade cloths the long way top to bottom on pic instead of side-side (just would need 1 additional shade cloth...no problem!)View attachment 3031228
I know you're aware of the threat - once a hawk sees chickens they know they are there. They will hang out and study the layout. So I'm afraid that the tall pines might work the other 'way round too, for certain species of hawks - might be how they hide themselves from the chickens before attacking.
