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.
Eastern Bluebirds may have 3 or 4 broods, Western may only have 2 or maybe 3. Other species of cavity nesters are different. For example, Tree Swallows and Chickadees typically have only one brood per breeding season, regardless of the factors above, unless a nest attempt fails.
