I would really appreciate help regarding a new chicken my partner bought me two days ago. It was sold as a 17-19 week old copper black maran pullet. It looks cross bred to me, from the photos I have seen online... also the neck feathers are pretty pointy, but it doesn’t have obvious saddle feathers... The legs look pretty scaly for a supposedly young chook but that could be a breed thing? I have the chicken in its own pen (as a quarantine measure, and to slowly introduce to my existing flock, who are old and a bit cranky). I have watched it a bit yesterday and today and it looks really sick. I haven’t found any poo but it looks dirty around it’s bottom- pasting, I think it’s called? It’s comb looks a bit pale and spotty. It’s exploring only a little, eating and drinking only a little (wouldn’t try kibble or porridge, but had some fresh scraps and some egg scrambled with olive oil). It’s mostly sitting hunched with it’s eyes closed, gasping every now and then. I think it’s right nostril might be slightly runny. What should I do, please? Can anyone sex/age it too? I would love if it is a copper black Maran pullet at 19 weeks... but I’m not too confident!
