I am having a problem with scissor beak in my silkies.It started showing up last year,may one or two, and this year I have had 6 with it.It shows up late in them,maybe 2 to 5 months.Is it genetic or are there other causes? This is very dishearten for me as they have to be put down as I dont want to pass this on to chicks.Does or can the rooster pass this on or is it more then hen? I have over 40 so it would be hard to pin point who is passing it on.I hope someone can help me figure this out and or give me some more info on it
