I see an ad on Preloved for someone local selling show quality chickens of all different breeds.
Made contact and went to see these chickens with boxes.
I kind of knew when I stepped in this blokes back garden to be faced with 300+ chickens it probably wasn't the best set up. Normal/average sized garden. But the chickens looked alright to me. I should know better, I've been keeping chickens for nearly 10 years.
Every scrap of garden was a home built aviary with chickens everywhere.
I came away with a Brahma, a Favorelle and a RIR. I picked out the first 2 specifically - pointed at the birds and said I want those ones. The RIR was in a pen with about 40 young birds of different sorts, 6 of which were RIR, the other 5 much darker than the one I've got.
When we decided what birds we were gettign he went to fetch a RIR while I went to get my box. So I didn't see him choose it and never really took much notice of what he was putting in the box.
I get it home and thought that it doesn't look much like a RIR.
I posted on Practical Poultry and everyone said they think its a cockeral (its only about 10 weeks old). Plus people have said it looks sick. 
I only paid £10 for it so not the end of the world apart from I have a bloody cockeral that I can't keep. Which is why I stopped hatching eggs under a broody as I can't face killing them. And I'm worried about what might be wrong with it for my other birds. I'm so bloody stupid.
