as an experience MP keeper, is it ok to keep only single mata puteh?..@ should i find another one to encourage it to sing?..
Sorry, just saw your post today.
I think it is perfectly ok just to keep one...... but as you put it, more will sing to each other. But I find it over rated, as after some time, they know their neighbours around and not so don't really get all worked up
Keeping one only, I still find that they will sing (buka) especially morning and evening and anywhere in between.
