Wyandottes are easily tamed and tend not to fly. It says that they are strong and vigorous birds and very placid.
Araucanas are placid and hardy and I can't find anything about the Legbars.
If you're new to all this I'll just put a few bits of info for you due to learning the hard way over the past couple of years since getting my hens:
Worm regularly - Internal parasites can severely debilitate birds and even kill them - signs that a bird has worms will include: diarrhoea, laying soft shelled eggs and generally being off colour - Use a product called Flubenvet. You can buy this online and just mix about a quarter of a teaspoonful into their morning feed - get some cheap frozen sweetcorn, cook it and then cool it. You can also sprinkle it onto some catfood if you like. Worm every few weeks, or if the birds seem off colour or have diarrhoea.
Don't use a product called Verm-X. It's marketed as a wormer, but it doesn't actually kill the worms. It's made from herbs that may make the gut more hostile to the worms, but isn't effective as a wormer.
Don't use the mite powder - that doesn't work either. I found the best product was called Ivermectin and I got it from the vets. This will kill external parasites and also worms, including gapeworm.
You can clean/disinfect the roosting area with a steam cleaner and/or bleach. These will kill redmite. Spray afterwards with Permethrin - buy it from the pet store.
Coccidiosis is another common ailment - some chicks become resistant to it, but others don't and it follows them into adulthood. I use Coxoid to treat this. It is characterised by a sort of greyish diarrhoea and a persistant dirty bum. It will eventually kill if left untreated.
Sneezing and being generally unwell is usually mycoplasma - my light sussex came to me with this from the breeder and the vet prescribed some oxytetracycline and it dealt with it pretty quickly. Oxytet is cheap and comes in tiny tablets that I pushed into a piece of sweetcorn for her.
Birds can hide the fact that they're sick very effectively, so sometimes a bird will seem okay one day, then go quickly downhill. Spend time observing them each day and get used to their individual characteristics and behaviour so you will notice if something is wrong. I lost two of my birds quite quickly due to internal/external parasites - they were in a poor state when I got them, but, being new, didn't realise and they died. I also relied on Verm-X and mite powder, neither of which worked 
The first year was a steep learning curve.
Foods I found they like: sweetcorn, rice, couscous, frozen mixed veg, spring greens, mashed potato and general kitchen scraps. Don't give anything salty or spicy or any junk food.
If you want to minimise poo and improve gut health, get a product called Orego-Stim - I got it from Rob Harvey and it's not cheap, but the bottle lasts a long time and it really helps cut down on the amount of waste they produce and also minimises smell.
If you need any advice, particularly relating to health, go to the Poultry Garden Forum as the people there are very helpful and there's lots of info. Happy Chicks sells lots of useful products and the lady who runs it also gives advice and the delivery of the products are super quick. Flytesofancy is another good site for stuff.
