I have Alcazar in a daycare w/ me.The older children know the boundries. The babies dont.It doesnt seem to bother him when the babies go to his cage.He just looks down at them. I think because he is higher up he doesnt mind but when it coms to the older kids that are eye to eye level his feathers ruffle and the children even know at that point not to go near him.Still the children love him they enjoy his sounds of dog, cat except during video day there is alot of....."Be Quiet Alcazar, Miss Toni can you cover him up?" LOL....As for if a child ends up w/ alergies in my case it would definently be the child to go. I can make that choice its not my child. Yes Alcazar did nip a child once and that child never put his finger in again and the other children saw and they know not too and they know not to place a chair near him because he will grab there hair and pull. If I felt real danger coming on then my choise will be to get a baby gate for his area. What the heck is one more baby gate.
