It seems that you just cant go wrong crossing a RIR rooster with any hen from what i have read lately. Is the hype true? Will it really up egg production over a standard breed hen? Today i was offered a rir roo and jumped all over it in hopes of better genetics in my flock. What i have is 7 gold or red sexlinks (i cant tell the difference by looking) 2 buff orpington rir cross, a black austrolarp, 4 rir chicks, 5 barred rock chicks, and 7 mixed chics from my flock. If im not wrong, i should get some good egg production birds here. Maybe some black sex links, rir, and some 3/4 rir chickens. Is there any downside? If i had a couple rhode island whites or silver laced whatevers id really be in business!
