When i got mine home they would eat every feather on the brooder floor they could fine, it drove me nuts trying to keep them dirty old feathers picked up, i upped their protein to 20% flock raiser and added scrambled eggs and keep a pecking treat in their 24 /7 and no more father eating, i have never had an issue here with birds eating others feathers or crest but when i see spindly cres and no new one erupting i check when they were wormed last as i believe worms effect feather growth of peas and the crestMine are eating their crests all the time![]()
would be the first place you would see such a thing as they stick out.
