You had better chose the cages and equipments according to your bird species. If we use unsuiatable equipments, the bad living conditions affect the mood of birds and then we can not spend a good breeding season.
There are different cages for difference canary species. We must care to be easily cleaneble cage when we chose cage. Therefore wood cages are not useful for us.
Wire mesh of cage should be vertical for canary.
An other important point for our canary coop, if we buy a new canary, we had better quarantine the new birds before we put it into the coop. Therefore we had better have the quarantine cage.
If we want to breed nestlings, we should have cage which has multiple breeding area. Thus we can prefet to buy multiple system cages.
