Thanks Tweedy, not got any blacks as I assume they would be easier to get the cuckoo barring , at the moment he running with a wheaten and crele hen, the cuckoo pullet is this years (may) hatch so think she bit young yet.
The neglected two are doing well, act like a proper old couple, he alot better on his legs and runs for his wheat, not getting rid of much of his weight though as he not that active although he does run for his wheat
The little furnace hen laid 11 eggs so think they happy now
I bought Dr Battys new book breeding oeg type and colours, very informative and has helped me alot, still confused with the colours though! Still have four books now so maybe one day the penny might drop
