I had some baby starling fall into my coop from a nest in the rafters they too are considered pests but I couldn't bring myself to kill them so let them be. The two of them actually survived and one i called wittle chicken hung out with me and the chickens untilmid summer I now have a feeder for the wild birds outside of my Bantam coop and am hoping wittle chicken will come to visit this year. I also hung a small birdhouse at my coop in case she wants to come. Raise a nest full of wittle chickens. I have become a sucker for birds of almost every kind since I discoved the love of my growing flock. I suppose if any fall in to the coop again I will take a more active role in their survival and less passive as before.
