If you had a positive experience with crevecoeurs, I think you'll be OK with polish. They are similar enough I don't think you'll have any big problems.I'm starting to feel worried seeing so many negative Polish postings (flighty, crazy, dumb, not cold hardy, poor health...), cuz I recently ordered some for the spring. I'm really drawn to crested birds and currently have 3 Crevecoeurs who are smart, inquisitive and sweet-natured. They are definitely flighty and resistant to handling, but do seek human connection on their own terms. I figured that Polish would be similar and after researching them for a while, I couldn't resist adding a few to my flock. Now I'm not sure that I made the right decision-- I've read they can be difficult to integrate, as well.
Has anyone had a positive experience integrating and managing Polish hens?? My birds don't free range and my coop is very secure. Eggs are not a big concern for me, either. My chickens are pets first and the eggs are just a nice bonus. I'm more worried about them being dumb and wild, causing feather pecking issues, or infecting my flock with lice. Any words from Polish owners to make me feel better or worse?

I have only ever integrated a polish chick as well as some others into the main flock but I can't recall anything going wrong. She was probably bullied more than the rest but then again she was in a flock of mostly non-crested birds
