Yikes! Newbie-to-be here... I came on to ask a few questions and am seeing such sad news (which is generating more questions, too)... So sorry for everyone's losses.
We are preparing to build a coop and get some laying hens in a few months, and I'm going to build a garden at the same time. I want to get rid of the oleander in our yard and replace the one that will be near (or in, not sure which yet) the run with a fruit tree. I know avocados are no good for chickens, but would a citrus tree (lemon or grapefruit probably) be okay there? I don't want to plant anything that will poison them, even though I've seen many people post that they don't worry about their chickens eating poisonous plants. (There is also a mesquite tree growing there which will provide shade -- I'm assuming that's not poisonous to chickens, right?)
Also, since so many of you are having coyote/wildlife problems... Are you in suburbia (like I am) or more out in the open? We have lots of hawks (and a nice light pole where they like to perch and plot their next move, right outside our back wall) and coyotes, foxes, and javelina who come through the neighborhood using the street behind our house to get to the wash, which is about a quarter mile down. Our yard is completely fenced in with a 6 foot block wall -- is that enough to keep the non-flying types out? I'm planning to cover the run with hardware cloth or chicken wire and maybe a tarp or a little bit of roofing to keep some areas shaded and drier (but not sure how necessary that is, since we are in the desert....) and figure the cover will keep the hawks away.
We have lots of ground squirrels in our yard and packrats in and out, so I figure if the wildlife haven't come over the fence for them, would they make the effort for chickens? Or is 6 ft high enough that they can't make it over?
I've been searching around online, and am having trouble finding good info on this stuff, especially the trees/plants so I thought I'd ask here since you all are the most likely to know about both chickens and the climate.... Thanks!
