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.
After ALL of the eggs have been laid (usually 4-6), she then begins to incubate them for 13-14 days, taking breaks to go feed. During the week while the female bluebird is egg laying she spends very little time at the nestbox, so if you see eggs and no female around at this time do not conclude the nest is abandoned.
