If a woman explicitly separated vow birds from obligation birds, but the priest forgot which were offered above and below, what is the general remedy?
Because designation was explicit, uncertainty about actual placement can leave obligations unmet, so additional birds are brought to satisfy all possibilities.
Question 2
When the vowed species is forgotten (turtle doves vs. young doves), what must be done for the vow?
Since the original specification is unknown, both species are brought so the vow is definitely fulfilled.
Question 3
What principle governs a required bird pair for one obligation?
A halachic pair is species-consistent; mixed-species pairs do not satisfy the requirement.
Question 4
If there is also uncertainty that her childbirth burnt-offering may have been a lamb, what is added?
That doubt introduces a possible wealthy-obligation track, so a lamb is added alongside the bird set that covers remaining possibilities.
Question 5
How are sin-offerings brought due to these doubts treated?
Doubt-based sin-offerings are not consumed; they are burned.
