They are loud! Which gives me constant anxiety because I have problems with my neighbors who hate chickens. My Barnevelders yell the egg song before, during and after laying, and also if another hen is in the nest they want, they will yell the egg song at her until she leaves the nest (if she doesn’t leave, they’ll squeeze themselves in with her and muscle her out). They spook easily and scream the alarm sound over dumb sh**

And often they’ll just screech for no reason at all. They don’t really have a normal conversational voice like the other hens, they just screech, which can be pretty annoying. They are also naturally skittish and approach the world with suspicion. I have put mine through extensive socialization since hatch, and they will hop up into my lap, but they avoid being touched or picked up (won’t put up a fight and I can catch them easily, but they’ll evade for as long as they can). Their breeder says that that’s a lot more than she’s been able to get out of hers. Hers keep a distance and won’t come near. So, I’ve accomplished a lot and it’s still doable, it just takes a lot of work for very little payoff. That’s if you want pet chickens, of course. I do, so the Barnevelders wouldn’t be my top pick. Honestly, I got them cuz they’re so pretty

They’re not much good for other purposes either though. Not quite pet material, not good for eggs because they only lay when they feel like it, their eggs are TINY even though they started laying 5 months ago, and they really make you wait for that first egg - mine were 9 months old when they laid their first. And they don’t lay the dark chocolate eggs that standard (red) Barnevelders are known for either. The DSL lay ordinary light brown eggs, so they don’t even have egg color going for them.
So, not great as pets or for eggs, and not ideal for meat either because they are very small even when full grown. What’s left is their looks, and they do have that going for them! They get a lot of compliments, and I enjoy looking at them.
The Orps, on the other hand, check all my boxes, so they are my all time favorites - calm and friendly, not easily bothered, very quiet, enjoy handling, lay well and lay large eggs, have a lot of meat on them, and my English varieties are pretty to look at, too.
