The number of eggs that a female owl lays depends on the species of the owl. Barn owls lay five to six eggs, while screech owls lay three to five.
Barn owls make their nests by using undigested materials. A female barn owl lays an egg every couple of days. The month-long incubation period starts once the owl lays the first egg. The female owl takes care of the chicks until they are old enough to leave the nest at approximately 3 months old. Female screech owls follow a similar pattern, but their chicks can start leaving the nest earlier at around 2 months old.
