Hello. I’m new to this forum and look forward to learning from those who have more experience. I had a nesting pair of bluebirds which hatched five young. The female disappeared when the hatchlings were about three days old. The male has been faithful to feed the young and I have been supplementing him with mealworms. He seems to depend on this. Although he’s better at feeding than removing fecal sacks, they should be ready to fledge next week. Anyone else had a similar experience?
