Hi, so my chicken yard is complete finally. Cattle fencing (I think) covered with hardwire mesh going a ft into ground. A canopy of tree branches overhead for excellent shade. It’s huge space and just perfect. I covered the yard top area in netting for aerial predators. Sigh before I put up the netting cardinals made a habit of eating left over scratch/feed once my chickens were in the coop. Now that the netting is up, baby cardinals are getting caught and tangled in the netting. I’ve rescued 3 in two days. I’m thinking about putting a bird feeder near the run, maybe that will help? Anything I can do to prevent these babies from doing this?
