So I'm not doing a repeat read my post #3910. Security has to be during the daytime as well. But after all this thread's experienced advice it's still your choice. I like that you got a one-breed flock of RIRs. Because they are assertive and a bigger dual-purpose breed they tend to be alphas in a mixed LF flock - but when they are an all-RIR flock the squabbles will be equal with fair challenges. Not to mention the benefit all those frequently layed XL eggs!
