We put chicken wire underneath the bed and well around the perimeter. On Monday afternoon, we noticed a baby rabbit inside the chicken wire! Turns out, there was a rabbit nest that we BARELY (unknowingly) missed with the tiller. Thank goodness, because that would have been....just....a huge mess.
So there are four baby bunnies in the yard. There is an adult who stays nearby and feeds them twice daily. They are really cute. They are unable to get to the garden, but just bask in the sun.
