Well, here's another "our chickens are fighting" thread.... We have an established flock of four laying hens - a Silkie, a Rhode Island Red, a Barred Rock and an Americana. All have gotten along nicely from the day we got them from a friend.....the Silkie tends to get picked on, but there is rarely any kind of fighting. We recently added two 4+ month old hens from another flock - one Maran and one light Brahma. They are close to the same size as our other chickens, though larger than our Silkie. We introduced them, after being quarantined, by adding them to our coop, but separated the new hens from the other chickens with the use of a large dog fence that divides the run in half. After a few days of watching the chickens and not seeing any aggressive acts, we quietly put the new hens in the roost at night without any issues. But first thing the next morning, found that most of our other chickens were aggressively going after the new hens. The Silkie in particular (she is most likely has been the bottom of the established pecking order) has been very aggressive towards the new hens and has drawn blood by pulling out tail and leg feathers. And once blood was spilled, the other starting pecking at the new girls too. We quickly separated the chickens again by again using the dog fence. The new hens look a bit scared and tend to avoid being too close to the dividing fence as the Silkie is pacing back and forth and will try and take a peck at them if they are too close. A bit of Vicks on the new Hen's tail areas seemed to keep the flock from pecking for enough time to allow the blood to dry. We have checked the feed situation, and our chickens are eating 18% protein chicken feed, and they also have Chicken Scratch and Oyster Shells mixed in. We also added treats in the coop when we tried to integrate the flock, but that sort of distraction did not seem to stop the aggressive attacks. We have also let all the chickens out to play in the garden, and they all played very nicely, scratching, having dirt baths and looking for bugs. There were no hostile acts and all seemed fine. As of today, the three existing hens (minus the Silkie) do not seem too agressive towards the new hens once back in the coop, but when the Silkie was reintroduced, she made a beeline for the Brahma and began pecking away. We know the Silkie is small, but wow, she sure seems to pack a punch! We understand that some pecking is normal to re-establish a new pecking order, but we are having a hard time standing by and watching blood begin to flow from our new hens. What should we do? Give the hens more time to become used to each other in their separate areas and have them "play" more outside of the coop? Keep trying to put the new hens in the hen house at night and hope for the best the next morning? Separate the Silkie on one side of the coop, and let the others be together since they seem to be less aggressive? Any ideas would be greatly appreciated!
