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 does it take for a parakeet to hatch an egg?   If she sits on it right when she lays it 18 days if she sits on it after the second one is laid then 20 days for the first to hatch and 18 for the second one to hatch. Tâ¦hat's just an average but seems to ring true. Making the world better, one answer at a time.
