Boswellia may stimulate blood flow in the uterus and pelvis. It can accelerate menstrual flow and may induce miscarriage in pregnant women. Other possible side effects of boswellia include: nausea; acid reflux; diarrhea; skin rashes
Bluebird nests usually contain four to five eggs. Clutch sizes range from three to seven. The number of eggs in a clutch is often related to the age of the bird laying them. First-time nesters often lay only four eggs.
A mother songbird usually lays eggs just prior to or just after sunup, but not all at once. A wren may lay one egg every 24 hours, a dove one egg every two days. The mother eventually will lay a clutch of three or four eggs, sometimes more and sometimes fewer. University of Cambridge researchers discovered a few years ago that mother birds begin communicating with their chicks even before they hatch.
