thanks folks
I know the dealer website but wondered if there were any others more local as my chap in Fife isn't on the list but Peter S gave me his details.
oh well, looks like it'll be some RIR's that might have to be introduced to some feather dye...NOT!!
However I have heard of somewhere where I can get RIR/Barred Plymouth Rock x's but they obviously can't be called Black Rocks so might go for them as at least they'll be black & me current chooks might accept them quicker
