Please can anyone help ive got some blackbird eggs and im wondering how long it takes them to hatch?

Question

there is 3 in total and they have been here for about 4 days and nothing

Answer 1

try siting on them,,,,,and why are you taking birds eggs???

Answer 2

Its not likely that they'd hatch.  You need an incubator, and the right humidity, and you need to know they didn't die between you taking them and putting them in the incubator.  And you need to know how long they've been sat on so you can turn them the right amount.

May I ask, what on earth are you doing with blackbird eggs?

Answer 3

it takes around 21 days but you should not have black bird eggs and if you have taken them from the nest you are bang out of order
