I just woke up this morning from loud, high pitched BGAWWK's coming from the silkies. I looked out the window and I saw Olly chasing Snowball, and they are both sisters.. I also noticed when Olly came by snowball, Snowball kinda puffed out, stuck her butt in the air and put her head down?? Even when snowball is eating Olly comes a long and starts pecking her. I think they have calmed down know but what was going on? Thanks.
