Dear Carnivores of Lucknow - A few queries

Now that I am settled back in Lucknow, I am looking to start cooking again as it is great for my mental health. I needed some help with sourcing meats.

Now for mutton I have the shop my father trusted for 50-60 years and for fish there is Narhi market + Fresh Choice. For Pork, Meatigo shows it can deliver.

I need help with two specific things:

1. Chicken thighs with skin - This is a challenge on apps as well as stores like Fresh Choice. Is there any local shop that sells these by kilo? I can only find skinless options.

2. Buff - Is it safe to venture out and buy this or should I avoid? If yes, from where can I get it? I know I can order cooked buff dishes but I would really like to cook some Irish style hearty stew with potatoes and veggies. It's perfect for this weather.
