This is super common though. I mix up my kids’ names on a daily basis, it’s not because I don’t know who they are or can’t tell them apart. They do think it’s hilarious when I mix them up with the chickens.
The common factor is that I am usually saying the same mindless stuff to my kids (and chickens), like “get down from there” or “move out of the way please” or “stop making so much noise”.
Think about predators - everything: rats, cats, dogs, hawks, mink, snakes, raccoons, foxes, bears, alligators, human thieves etc - depending on where you are. They taste like chicken. Can you predatorize the coop or will you accept a certain rate of loss (be aware that once they know the chickens are there, they’ll be back). And what are you going to do with injured, not dead chickens?
Our run has hardware netting on all sides including the top and under the dirt, and we let them out in the garden to live their best lives when we’re at home. So far this has kept predation down although we have had some curious cats.
Also if you have kids think about whether your chickens are livestock or pets. Ours are pets that lay eggs.
