Oh my goodness!! Poor bird. A lot of huge-crested silkie owners use rubber bands or hair ties to tie up their crests.I have a beautiful young black Silkie pullet, a few months old and this week she started acting really strangely. I was trying to figure out what was wrong with her. She was standing in the corner of the brooder, only drinking, I did not see her eat. The 3 other Silkies were not picking on her or anything. Her crest had come in so full that I started to realize she was totally blind! I could barely find her eyes in all that fluff. I tried to trim it but my scissors are useless, so with some aloe I slicked back her crest. She is starting to eat a bit now. She was drinking a ridiculous amount of water just because she knew where it was. Poor girl! I knew the crest could affect eye sight, but never thought it could make a bird completely blind!
