So you are after behaviors. I wasn't sure what you wanted from your first post. I'll link Henderson's Breed Chart so you can read what they say about these breeds.

I consider this chart a compilation someone put together together from research and with some personal experience from their own chickens for a few breeds. As you can appreciate, it is a huge effort. I do not know what their sources were. For averages to mean anything you have to have enough samples. If you only have one or a few then you could be way off from the average.
In my opinion, strain (or line) is very important in any of this, probably as important as breed. For example, you obviously want the really dark egg genetics. If the breeder is selecting which birds get to breed based on dark egg genetics you can get a line that typically lays really dark eggs. If that is not a criteria, say they are selecting which birds are more likely to win a breed show and don't pay attention to eggshell shade, then you are less likely to get really dark eggs. Even if your line typically lays really dark eggs you can get one individual that just doesn't. Or one that takes confinement well even if most don't.
Information from this or similar charts or observations by people that have those breeds is probably the best you can go by. Information about certain lines could really be important if you can get it and trust the source. Good luck!
This is what I'm talking about. Some strains of RIR's can be aggressive. Some are not. Somebody on here had an aggressive RIR so now all RIR are supposed to be aggressive. You know form experience that not all are.
