I only have guineas, so I can't really speak on other birds, other than things I've noticed.
Chicken eggs are considered the easiest to hatch & in the shorter amt of time, but more susceptible to disease. Acquiring feed for them is easier, and some feed them table scraps.
Conversely, even in the states, I was having to have turkey/gamebird starter shipped to me for the 1st 3 seasons. Local TSC finally caught on this fall that it might be a good idea to supply food for birds they sell

. The eggs are easy to incubate, but far more fragile than chickens in their 1st week of life. Once they get through the 1st 14 days, they're very resilient birds less susceptible to diseases. (They're also very loud).
So if quail have special feed, take that into consideration. We've been trying to help someone else in another ctry figure out how to supplement bc special feeds aren't available, nor can it be shipped to her.
On the other hand, quail are small, and from what I've read, thrive on human attention where as guineas would prefer to be left alone.-or so they say.

mine have never mentioned it. Likewise, it seems like chickens are more domesticated as well.
So your choices shld be related to
1. Space - where are you keeping this bird when it's grown?
2. Access- feed requirements & possible medications or treatments
3. Purpose - are you wanting eggs, meat, or a pet?
