Do you plan on gardening, flowers and/or veggies, in that garden?..... My plan is to only have them in the garden when I'm home to supervise them......
...UGH!! I'm thinking that I think I'm overthinking my thinking!!.....
Birds of prey(who can still attack despite human presence) and the chooks flying over might be the least of your worries......
...the chooks can make pretty quick work of tearing up plants.
So you might have to plan on fencing them away from your plants....just too give you something else to think about.
