I have 4 hens and a rooster, I have had them for about a year, Ive had them as babies, I didn't want a rooster but surprise! i have one now...I just rescued a new hen she is the same age as my chickens. shes a leghorn... I have been putting her in a dog kennel at night and letting them all run together in the yard in the day time. the rooster tries to beat her up shes terrified! and I also have one mean hen that beats on her too. what do I do??
