Jersey giant bully silkies

[Watermelonteatree]

Hi everyone, I would really appreciate some help with our small flock!

We had two silkies and two jersey giants. They grew up together and have always been friendly to each other. A couple weeks ago (when they are around 4 months old), we had an accident and lost one silkie.

Now we are left with two jersey giants and one silkie. The silkie is getting more timid and we saw on camera that she was chased by one of the giants repeatedly throughout the day.

I read something that chickens always peck on the one different chicken in the flock. Could being the only silkie started the bullying?

Big chickens pick on smaller chickens, and the silkie is smaller and 'different'. The chicken social order is frequently not kind.

What was the accident?
Are the JG both females?
