Is this a good idea for arguing parrots?

[JaydeParrot]

I have two Senegals, usually they get on alright together but lately they have been arguing a bit, acting like their going to bite the other's toes and at one point one actually climbed on to the back of the other, they did look funny, sort of like a parrot version of human pyramid, but the one at the bottom wasn't happy, it growled angrily and refused to be around the other for a while after I had convinced the one on top to step off on to my arm.

They came as a set and were untame and very tightly bonded when I first got them, I wonder that as they have gotten more tame they have had time to argue more or something.

I figured maybe I should put one in one room and one in another room for one night a week, so that they miss and learn to appreciate each other more, they do say familiarity breeds contempt.

I know parrots are smart, but am I thinking this through too much?

Is seperating for an night (8:00pm to 11:00am) a week a good idea or are there any problems to be considered?

Are they male and female? Because, if they are, the one on top might have been trying to have sex while the one on the bottom did not want it. Are they kept in the same cage? Because even a married couple who love one another would get on each other's nerves if they had to live in the same bedroom all day long every single day of their lives. Do they get, at least, four to five hours of out-of-cage time a day and one to two hours of one-on-one time with you consistently? Because, if they don't, the problem is not them but you. Are they clipped or fully flighted? Because birds that are allowed to fly are much more even-tempered than clipped ones (flying dissipates stress hormones). Are they free-fed seeds, nuts or pellets? Because, if they are, you might be feeding way too much protein -which makes them hormonal and bad-tempered. As you can see by my questions, the information you gave is not near enough to make a good, educated guess of what the problem is so we cannot give you a good answer to your question. But I'll tell you one thing, though, birds do not wake up at 11 am so they might be exasperated by the weird schedule you are keeping them under...
