Thyroid -- how much to eat?

[Beyonder]

So I just got this giant cow thyroid - 1 lb. I've gotten thyroids in the past and they've been small and I've eaten small slivers at a time. But now I have this big thing and my question is:

1) Are cow thyroids really big, or is this a thyroid encased in a large fatty membrane?

2) I don't want this to go to waste, but if its not safe to eat that much thyroid then I'll probably have to dispose of it at one point or another.

Seems like it's a pretty big gland... not huge compared to the cows, but cows aren't small.

I couldn't tell you how much to eat or not, but I'd think everything would obviously be different when you get the whole gland vs if you had dried or ground thyroid.  To go with the general feel of the forum I'd say start small and if it doesn't cause problems, you can try some more.
