How many lamps are you running? I've had trouble keeping large numbers of broilers warm during early spring in an uninsulated brooder building. I only brood them now during the warm season since it's so much easier. In certain setups, heat lamps can cause convention and in cold temps that...
I find dual purpose birds get pretty tough and stringy meat after about 5 months old. You can cook them differently when they grt older than that, but it's more complicated and less like the store bought chicken that most people are familiar with.
Don't chill the birds before you eviscerate. There's no point to that and it will make them much harder to eviscerate. A warm bird is pliable and loose, a cold one tightens up stiff. You can line up a bunch of scalded and plucked chickens on a table and let them sit for 20-30 minutes while you...
I tried using a cone for the first two I did. They are such fighters and their wings are incredibly strong...mine would roost on the peak of my two story house regularly. I tried tying their feet and hanging them for the kill cut, but it was too chaotic. We eventually just landed on chopping...
I'm going to start with brahmas, australorps, and buff orpingtons this coming season. Along with a positively large WelsumerXEasterEgger. My ultimate goal is a friendly, cold-hardy, large-bodied, landrace hobby breed. But I have lost so many birds to mink that I don't know if I'll ever really...
Sounds like you have some fun projects going. I have no idea what type of meat you might expect from a ayam cemani or any cross of one. I would say that meat looks really dark though. Was the skin similarly dark either before or after cooking?
I'm also waiting for some brahma pullets to start...
Id recommend texas poultry shrink bags. The owner started the company as a high school project. Must have been ten years ago now, but his business is well regarded and he's obviously done his market research because they are thick... I've never had a second thought about tossing a hundred birds...
I have not, but if you haven't looked into heat shrink bags I would recommend it. They are a huge jump in efficiency from vac sealing in my opinion. I still vac seal when I freeze cut-ups and I vac seal venison, but the heat shrink bags are the way to go for whole birds.
