Uh oh...never suspected it wasnt legal to just toss them in the trash-what with all the predator attacks we had this fall, I am pretty sure our garbageman suspected we were having weird animal sacrifices or something....
I don't know if this would work for you, but when one of our Rhode Island Reds got prolapse and died, we put her in a plastic zip-up bag and put her body in the garbage bin.
Not the most respectful burial, but it is what it is.
