Found these six robin eggs in the hanging fern on our front porch. Walked outside to pick up a package and saw the bird fly out of the plant. The main picture was taken on the 8th.
Here’s a picture of them from today. All six eggs are still there, but they have not hatched yet:
I don’t know this exact species, but cuckoos usually monitor the nest. However no matter what, original bird’s offsprings wont survive as they will be removed. If the cuckoo “retaliates” it wont change anything. Its better to toss the egg and monitor the nest.
