My aviary contains the following birds:
budgies (about 15)
indian ringnecks (1 male, 1 female and 2 babies

kakarikis (1 male , 1 female)
ringneck doves (5)
i think there is no problem in planting a pine tree inside the aviary because i use pine shavings for the nesting material of my birds and there is no problem with them, can someone give an opinion ?
