Hi ALL! Just confirmed vent picking and some neck picking by the 2 "Boss Hens" which are large Black Sex Links picking on our other 4 Rhodes Island Reds. Thanks to Carrie, a poster here at the forum, who made the suggestion since this is our first flock. We have separated the 2 Black Sex links for the time-being but need to know how to curb the nasty habit. They have a large run and coop and and not free-range. They have a red heat lamp if they need to get warm but noticed the pink bottoms around the time we had a cold spell in Upstate NY...we weren't sure if it was a lot of laying or what but it was confirmed today when we watched them for a while and witnessed it. So, now that we have created this situation, how do we fix it? Any ideas and thanks again Carrie B. They always have lots to watch and visitors but we think those couple of cold days we kept them in the boring chicken coop condo may have lead to their boredom and then this pecking order disorder.
