Some roosters are aggressive to non-breeding hens. Those roosters normally change their attitude for the better towards specific hens once they are laying/breeding again.
It's not always the same, some are like yours- treat the non breeders as if they were another rooster. Others will at...
This is usually what happens with adding any new bird to the flock. They don't care this is a rooster, it's a new bird that needs to be reminded of its place.
The rooster is still young- that's the main problem. An older, mature roo would have handled those pullets very differently. He will...
X2 what chicmom said. Some hens are very attractive to roosters as if they were a beauty model. This is unfortunate if there is more than one rooster as she will suffer way too much attention.
If all three came from the same place and both hens lay WHITE eggs, they are all leghorns.
Clear white egg layers aren't common in backyard flocks so I'd say that is a clear marker of a leghorn, even if they have the wrong leg or earlobe color. I've seen definite leghorns with pale legs or...
Oh sorry missed you already had a coop. I would suggest if the coop is very secure from predators, get her and her babies in there and lock them up for at least two weeks. Chicks are vulnerable to hawks, they would be exposed out in the yard, waiting until they are a little older improves...
That's a Sebright mix- rose comb and her patterning is normal result of mixing a laced chicken with anything not laced. Most likely a Silver Sebright mix.
If you catch her I would advise to keep her in garage or whatever for a couple weeks. Because she will become much wilder after being...

I agree, not an Ancona.
I wonder if mottled orpington is a possibility? Other than that maybe speckled sussex and a black breed mix(not cross, at least two generations away).
