Yes, I do, but some sensible precautions should be followed.
Select species that are reasonably evenly matched for size. For example I keep a Jardine with a rather small Orange Wing Amazon together and they get on quite well.
Introduce them gradually and watch for undesired behavior.
The pros for this are company and stimulation for the birds and obviously making the best of the space you have available.
The cons are that there is an ever present risk of a "fall-out" and resulting injuries. Parrots are like little kids, they bicker and argue!
It also makes monitoring of diet, what the bird is eating and not eating more difficult.
Yes. Make sure each bird has enough space to move around free and fresh food and water is provided daily.
I think they can but im not sure
no
Yes they do mate with different colours
yes
No, they are different species, like cats and dogs. They will not try to mate, and cannot produce offspring together.
No they don't, they are of different species and it is most likely physically impossible.
No. Two totally different species. In fact, the gerbil will kill the mouse. They shouldn't be housed together.
I believe it is impossible for a chicken and a turkey to mate together due to the difference in size. Being different species, it is also unlikely that they would have any inclination to mate together.
No that's not possible because different worms cant mate together. How could you not know that. I learned it last week and I'm in the 7th grade
Yes, they are the same species. Its like when a tiger and a lion mate they may have a different classification but they are the same species.
yes.
No, they are different species.
no
No, since they are different species, the resulting eggs would not be fertile. They won't even (mechanically) fit together.
