Last year I raised all Rocks, Barred, Partridge and Blue. And even though I noticed a difference in the individual birds, They are pretty calm and liked me! Now I have some 4 Barred Rock chicks, 2 Buff Orps, 10 Aruncanas (sp?), one RIR, 2 polish (white crested), and 2 silkies. The BR's are just like my birds last year, my Buff Orps are SILLY girls! They get all flustered over nothing. My RIR is one bold little girl and nothing flusters her, my polish are very curious and my silkies are shy. Anyone else notice things like this? My Aruncanas are kind of like my BR. But since there are a lot more of them, I haven't gotten a good lock on their personalities.
