I wouldn't worry to much about the comfrey. I learned in an enviromental science class I took about six years ago that potatoes are poisonous to us. However, you have to eat about twenty pounds or so a day before you see the effects. Who is going to eat that much? The same might be with the comfrey. Who knows. I have learned though that animals usually avoid things that will harm them. Deer will avoid poisonous plants, but every thing else is fair game to them. The chickens probably know what they can eat and what they can't. It's probably programed into them from the time they hatch.
