yea it is, but from what i have read it can be genetic or temperature flux - being a broody, not sure if maybe that might be a possibility- either way, i'll keep an eye on her the next few days while i try to decide what to do- its the bottom beak doing it- i did watch today and she is active and able to catch flies and eat- she will for sure not be used for breeding, possiblly in the house so i can monitor? not sure yet
i am sorry
thanks for letting me know.i will keep a record of it and also check with others who have some chicks.
