I have just rescued some birds. Got them as buff sussex. Lovely looking birds apart from missing lots of feathers after being with a cockerel and one is missing an eye (I think probably mating injury, although maybe wrong). They are doing really well learning how to forage, they were kept on concrete as the land they would have been on was clay. I am a unsure as to whether they are buff sussex or not. The only ones I have to compare them to are 9 week old cockerels from my hatch - sold the hens (unwillingly, but where children are concerned)! The new birds are completely buff from what I can see at present apart from the odd black feather in the tail, some also have 5 toes. The cockerel they were with was all buff aswell nothing like the ones I have. I can't find any pictures of Buff Sussex on the internet that looks like them. I am thinking maybe Orpington - not that I mind. But opinions would be good.
It has made me decide to make some hen saddle when I start breeding. I have already bought some faux leatherette. But then I have 1 hen and cockerel in the garden and she is ok even without the saddle. When they are fully feathered I will get some pictures of them and hopefully we will have more of an idea.
