Female northern cardinals do not experience pregnancy in the same way mammals do, as they lay eggs instead. After mating, a female cardinal typically takes about 1 to 2 weeks to build a nest and then lays a clutch of 2 to 5 eggs. The eggs usually take about 11 to 13 days to incubate before they hatch.
it left it to hatch alone
The incubation time for cardinal eggs, specifically Northern Cardinals, is typically about 11 to 13 days. The female cardinal incubates the eggs, which usually number between three to five in a clutch. After hatching, the chicks remain in the nest for about 9 to 12 days before fledging.
Leave them alone. They will hatch out by themselves.
They do not. The female takes care of the eggs till they hatch and then on the young ones are on their own. The parents have no part in taking care of them.They also leave their young alone...
Because female bettas will eat eggs and the male will fight anything to protect them. Never ever leave a female in the same tank after they're done mating, he'll probably kill her!
She needs to "hide" while brooding her eggs. If she was red like the males, she would be easy to see and be attacked.
