I have two Red Sex Link hens and have had them for a year now. Though their egg production is high, they're extremely aggressive towards my other hens and bite me as well when I go in to feed them. I even have to stay in their run while they eat or they continuously chase one hen in particular away from the food (I keep multiple feeding stations), even when they're not eating from the same dish or even interested in the food for that matter. When the hen they have targeted gets on one of the branches in the run, they lay underneath it either together or taking turns, preventing her from getting down for the entire day and if I let them out of the run to range around the yard, that same hen is more often than not too afraid to go back in at night, especially if they've gone in first. These girls were hand raised and were quite sweet when they were very young but became more distant as they aged and are getting increasing more aggressive every day. I enjoy spending time with my birds but not these two. They've earned themselves a one way ticket out of my flock and I won't get this breed again. There are plenty of other more docile breeds that lay very well - these just aren't worth keeping in my flock.
