These are my latest Roo's, Big Fella, Mr Gimp, and Mr T, The are all feral, and have adopted me, my original 2 boys were stolen last year and have not yet found their way home, they had straight combs and golden manes (they were a good size and very sweet) the sister, black, (sex linked?)she produced and raised these 3 chicks; one grey speckled with yellow legs the other 2 mostly black, previously the black were hens like the mum, the grey speckled with yellow legs became my 2 Roos. this time all 3 Roos! my query is, these 3 boys ALL have rose crowns? 2 look alike, one is golden. The only Roo's I see around have straight comb?what makes the difference? also the golden boy has small eye the twins have big round eye? they are all from the same clutch, I am sure there is Hawaii bantam in the mix? Big Fella is a little larger than the other 2. they are just starting to crow 2 out of the 3 . Any one have thoughts on this?
