I have recieved 3 crates of bosc pears that are overly ripe. How many of them can I feed my flock of 24 chickens? I've been cutting up the pears (about 4) with some of their mash.. They seem to love it but I don't want them to get sick. The pears will go bad in a few days. Should I just compost them or continue to feed the hens bosc pears and mash?
