No all it will do is dye the birds feathers a nice yellow colour that will help to attract the Hawks, used to dye my pouter hens with bleech years ago to attract the cocks but it weakens the feathers and can burn the quills.
Very well done to you and your wee Hen Mr Monk I would lock her away and not let her out again incase one of those wild Animals that live nearby you, eat her.
Yes Davie, seen them got to ground if they can't find any cover of trees to go into,but only if they are near the ground at the time that they see the Peregrine.
