I am sooo sorry for your hen!! Poor Baby!!
I'd do away with this rooster!! He is at the age now to see how he is going to be with the hens. You don't want a roo that will attack like this.
Sounds like your hen is in shock and even injured, maybe severly. You need to check her over carefully for injuries. He may have used his tallons (claws) on her to inflict puncture wounds that you can't see thru the feathers. The blood is coming from some where. Look closely to find the source. Once you find the source, we will be better able to tell you how to care for her. The turkey was just probably taking advantage of her in a weakened state. Once birds taste blood... they will go canibalistic and eat their own.
I once had a rooster that would be cruel to hens that would not submit to him. Those hens were treated cruely, chased around, not allowed out of the coop, not allowed to feed with the others, or even roost and sleep with them. And breeding was too harsh. Roosters like that are bad seeds and should be put down.
Your poor hen may have been treated like this and you just didn't see it....we can't always be there. After checking her over carefully for injuries or puncture wounds. Let us know what you find. In the mean time, just keep doing what you are doing. Let her know you are there and speak in a soft tone. I think she's in shock and maybe weakened from her overall treatment from this rooster.
I'd unwrap her from the towel. This may make her feel like she's still being restrained or attacked. Keep her warm, dry, and inside. Keep food and water at the ready in case she wants it. The first day is always the hardest. She should show some kind of improvement tomorrow.
Shock is a horrible thing in chickens/birds..... they don't always pull thru the shock of an attack.
I'm praying that she does and I will look foward to an update in the morning. I feel soo bad for you and you're hen. Praying she pulls thru!!!
