Elevated levels of homocysteine in the blood appear to increase the risk of heart attack, stroke, peripheral vascular disease, and venous thrombo'embolism (blood clots in the veins). Homocysteine is believed to damage blood vessels in several ways.
I don't know for sure about how long Wrens usually spend on the nest at one sitting.. (Sorry couldn't resist the joke) However, the eggs usually hatch in 13-18 days, so if there were no hatchlings when that time elapsed, then you'd know for sure that she hadn't been behaving normally.
How long parakeet eggs take to hatch? It takes 18 days of incubation so not 18 days from when they where born but 18 days after the mom starts to sit on the eggs. Typically new hens will start to sit on the eggs wâ¦ith the arrival of a second or even a third egg so don't be surprised by this.
