I am portuguese OP, but i do not currently live in portugal as i emigrated in 96. But i could translate anything for you if you require. just send me a pm with the info that you need translated.
I'm from Estremadura (center), and both my grannies raised small scale poultry, one in a farm, the other in her backyard in the city. I never remember them being concerned about any rules or laws in that regard, but then you are doing it on a different scale.
