So I have a very friendly and very tame Barrad Plymouth Rock Bantam rooster named Penguin and another Bantam, a very friendly and very tame hen whom we named High Hopes or Hope, whom I bought from a person who was selling his bantams. I had another Bantam hen who was skittish and not tame at all and was completely scared of people. Her name was Ebony. Me and my dad went up Friday to eat with my grandparents since we couldn't have Thanksgiving with them. Well my dads friend's sister (whom we got Penguin from as an egg because we hatch them straight from eggs so they are friendly) had some friendly females. I texted her saying we needed a friendly tame female. She texted back saying have one picked out. We picked up our new hen from her and named her Dusty. While driving home I texted her to explain why we needed another friendly hen. I mentioned Ebony (who is solid black) and how she wasn't tame enough for us. She said she wants and has been looking for a black hen because all she has is speckled Bantams. Well we told her she could have Ebony. So when we got home I had my dad hold Dusty while I caught Ebony and put her in a box to take her back up to her. I put Dusty in Penguin and Hopes pen and they both attacked her. Penguin was trying to mate with her but was still a little aggressive but Hope was aggressive no doubt. But the thing is Dusty is definitely a hen. The lady we got her from had the original two hen mothers and their children who were all the same age including Dusty and it was completely obvious to tell the roosters from the hens. Dusty looked just like the others that were hens so I know she is a hen. Its been two days and it progressed to where Dusty has to stay on the stoop off the ground where Penguin and Hope are. The food and water are down on the ground and I was watching them earlier and Dusty flew down from the stoop and onto the ground to drink and Penguin and Hope immediately went after her. I had to separately give her food and water. I don't know why they are doing this. Could someone please explain and help me find a solution?
