How long would I have to keep out 3 older hens to set a new pecking order? Remove all 3 or just one at a time? I have 3 year old (2 in May 2011) sex link hens that beat up on my 5 teen hens now for weeks now. The teens around over 20 month old now. The teens run when any of the 3 come near them. The 3 older hens will chase and peck the teens constantly. I was hoping attacks would stop as it have been closer to 3 months now. Also,now some of the teens are starting to squat,so when an older hen attacks the teen squats and get pecked over and over instead of running away. I was thinking to put the older girls in a metal dog crate in the garage for a day/night,and then add them back.Would the teens be more likely to hold their ground,or would I need to keep the older hens out of the coop/run longer? Last week I found blood splatter in the coop,but could not find any injury on the teens.I know someone got it bad. I need some peace with them,because they will be spending much of their time in a 6 by 8 shed for the winter. Should I mess with them or just ignore and hope no one gets seriously hurt?
