i am building my young bird cage ive not got a lot to do it is 10foot buy 3foot wide and 4foot high. it as two 5foot sections with a little door so they can have full run of the place it also as a wire floor to cut the cleaning down. i am going to put some perchs in soon but dont know what to use i was going to use 3,2 spares across the back but i think they may crap on the ones on the floor. i could make some box perches but want to avoid the cleaning due to the lung which be the best to use
