We brought home a pair of african love birds 2 weeks ago. They have suddenly become quiet from yesterday. we feed them seeds and fresh spinach & coriander leaves. they are in the same room as the TV. is this an issue?
When birds suddenly go quiet, something is wrong. I know you live in another country, so I don't know what is available there, but the diet does not sound healthy at all.
Please contact a good avian vet and ask them what they suggest you feed your birds. The TV will not suddenly make birds be quiet for days. In fact, the TV will often encourage the birds to make noise.
