Hisham bin Urwah narrates from his father that two sacrificial camels of Sayyiduna Aishah (may Allah be pleased with her) went missing. Sayyiduna Abdullah bin al-Zubayr (may Allah be pleased with him) sent her two others, and she slaughtered them. After that, the missing camels were also found, so Sayyiduna Aishah (may Allah be pleased with her) slaughtered them too.
