When will my broody hen's eggs hatch

[Peterpam33]

My frizzle went broody in March. I was still able to collect eggs from her. April 1, I no longer collected from her, and she was sitting on three eggs at that time. Today, (April 13) I moved her and her eggs to a quieter spot, and she's sitting on 7 eggs, three of which are not hers (azure eggs) When will these eggs hatch? 21 days after last egg was under her? I don't think she's laid since April 3rd but the Azure eggs are from this week.

Have a 'Plan B' in mind because she will probably leave the eggs within 36 hours of the first chick hatching. As to when the additional eggs will hatch - 21 days after they were added to the nest.

she would probably leave them so if you have a plan to hatch them you should see if any other hens are broody and if not put them in the incubator if you have one
