I have 4 silkies about 19 weeks old (among others) They are the only ones that I can easily pick up. They always run to me and if I stick my finger at them they sometimes gently peck at my finger nails. But today, one was biting hard. So I flicked her and that caused her to try to bite harder and jump at me. I pushed her back and flicked her more, but that only made her more aggressive to me (I know, I'm talking about silkies here). So I grabbed her and held her shoulders down to the floor, but then one of the others came to her defense and started trying to bite me. So I grabbed the second one and held her down too. But then the 3rd one started in on me. I only have 2 hands so I could only try to shoe her away with my foot, but that made her come at me more. (the 4th one left me alone). Do you think this was them being aggressive? I mean, they're silkies for pete sake?
