Homemade Suet Cake for Poultry!

Great detailed and wonderful layout here! Instructions are very helpful and clearly you are a creative and good teacher, making use of photos along with the write up. Thanks also for the links to the kitchen tools…no kidding, I need all of them, especially the form piece.
Suet is so good for the local wild birds as well as the migratory ones so I wasn’t surprised to see the sweet flock following me around last winter, though not sure if it was ok for the chickens. It was a go after reading in a chicken-mama farm blog that her chickens also were loving the suet she made for wild birds. She liked hanging shapes in the run for the chickens’ entertainment!
I really could have benefited from your posted article back then.
I started making a round of treats, using any sized lined muffin tins allowing me to break or cut the pieces up as needed, (removing the paper, of course), and keep another day’s treats in the freezer. I use the 50/50 % unsalted peanut butter/solid,(melted) coconut oil, and it works very well. 2020 was the lockdown around the world so I was not shopping much, thus tried out different ways to mold the suet, making use of wire suet feeders lined w/ parchment paper then the plastic containers suet is sold in. Favorite was the discovered single cake pan in my cupboards, like your molds, that worked like a charm.
Has anyone used a blend w/ the organic chicken feed of cornmeal or plain ground instant oatmeal? I throw in some fresh or dried herbs from the garden. I would love any tips on the best herbs. Imogene pup, our Rat Terrier, loves suet also so she has her own recipe without sunflower seeds.
Best regards, stay well, and warm!
