Would love to have you weigh in on this...I have 4 hens. One 2.5 year old buff orpington who is a total sweetheart, one black sex link that is 1.5 yr old and my best layer, one 6 month old barred rock and one 6 month old rhode island red. One of the two youngers is laying pullet eggs daily as of this week. We have an awesome run and coop setup that the older girls have been living in since July, even in our cold WI winters it works great! Everyday we put the little ones in a small run next to the big girls so they would get used to each other. Eventually we let them all wander in the yard unobstructed again to get "acquainted." Now that the temperature is dropping we cannot leave the younger girls outside unattended and have resorted to keeping them in a large dog crate in the garage and left the other two outside in our run/coop...where they have always lived. Here is my dilemma...my black sex link is a bully! Whenever she sees the youngers she attacks them. Even chasing them all the way off of our property. Initially we thought she was attacking because the younger would try to eat something she wanted or whatever...but last time they were out she just kept running one of the girls down over and over even when we interrupted and offered her a distraction. I am genuinely worried we won't get all 4 to live together. I can't stand the thought of the 2 living in our garage...just goes against why we have chickens to begin with. I am reluctant to re-home the BSL because she is my best layer AND my son loves her to death...we hatched her. If I have to I will though, so if that is my only option let me know. The other thing we tried after all the other attempts was to just put the 3 (BO and 2 youngers) in the coop and that went PERFECTLY! So what do I do? I am open to the current living arrangement through this winter if absolutely necessary and anyone things that would help (time)...but obviously would rather not...just not fun for those two young birds. Would love folks to weigh in...especially BSL owners...just don't know if it's a breed issue or what. Thanks in advance.
