Wrangler is getting new feathers---FINALLY...and has one large one poking through that is very uncomfortable for him midway on his back. It looks like its a significant sized feather, possibly part of the wing? (He wont hold still long enough for me to look). If i accidentally shift it while Handling him, or toweling him after his shower he lets me know. The feather tip has been poking out for several days now but he hasnt preened the casing off. Im concerned the feather may die. I'd prefer he take care of it himself but at what point--how many days--should I intervene and help remove the casing?
