I am curious if anyone knows what type of tissue the orandas cap/wen is. Also does this type of tissue have nerves in it? The reason that I ask this is that one of my oranda's can not see at all. The top wen has covered his eyes. Funny thing is that he still finds the food lol. However, his movement is somewhat erratic. Would it be possible for me to trim some of the wen if I was to do it correctly?
