So good to hear your hen is doing better! Ugh roosters! Stop him. Now. Roosters will be a guardian to your hens within their ability. No match for most predators, but sounds an alarm. Most roos quickly herd/call their ladies to the coop if something isn't right. They will defend and protect the hens, many are taken and killed by predators.. Teach the kiddos and family to toe him in the chest. firmly toe and push. Not to injure him, but firm! (almost a soccer punt but not a goal, lol) Enough to move him away. Keep repeating until he leaves/backs off, Another option is to embarrass him. If he is small, pick him up, Hold him firm, until he stops struggling. Big roos, Pin to the ground.on his back even if possible. I have body slammed my big gander, big boy no kidding, I am real small but I wont let a bird intimidate me. Some roos will not learn.so be prepared that he may be going to the freezer. They are saying to you that THEY are the boss. Since the flock follows you, he is trying to control his flock and your family is included. Every family member that's old enough must teach him otherwise. If everyone follows the same practice to stop him, he will learn humans are well above his pecking order. They are just beautiful little ladies I am a noob on colors & gene patterns too.
