I have gone from 4 birds last month to 7 at this time. I had Da Tielish Ones, Nibble, Piper and Dodger and Miss Riti, the Kakariki in four cages. Then I got Cheddar the GCC, in his own cage. 5 birds in 4 cages. But it wasn't too bad at least they were in one room and Dodger was itching to get in with Nibble and Piper in the Big House and he did so now I'm down to 3 cages. Then a friend had to have a knee replacement done so I have her Tiel, Miss Moneypenny and English Budgie, Winston. They are each in their own cage and in the livingroom her as I didn't have enough room in the birdroon/computer room for them. So now I stand at 7 birds in 5 cages in 2 rooms. It use to take 15-20 minutes a day to deal with the mess not it's closer to 45 minutes.5 The biggest slob it Winston, the smallest make BY FAR the biggest mess. One thing I have learned from this is I have too many birds here. 5 is pushing what I can deal with so having 7 is a quick cure for MBS!
