What kind of parrot is Valentine?
Almonds are high in fat, so they should be given in moderation, as an occassional treat or reward, rather than a regular part of the diet. I would recommend just one to three whole almonds a day. Or less than that, if you are offering other treats.
For smaller parrots, you can offer almond pieces, instead of a whole almond, but the total amount of almond should remain small.
