Once an old time farmer told me, chicken farmers used to pick up road kill and have their chickens eat the maggots off the road kill. He's also told me other things I've thought were whoppers.
The chickens will eat them and they love them! I didn't do a maggot farm, but it isn't hard to get them - I put out a bowl of left over tuna. It sat in the sun for a day or two and viola maggots! The chickens LOVED the maggots (I didn't give them the tuna I was afraid it was too bad by that point, but I am not sure it would have made them ill.)
That's disgusting. I can get past eating the eggs when they eat bugs, lizards, and even got past them swallowing some baby rats. But I can't get past the visual of them eating maggots and then me eating the eggs. Makes my stomach turn.
