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.
Chicks take 21 days to hatch, and a clutch of eggs can take a few days to completely hatch. Mark the date on your calendar! Any adjustments that need to be made should be done at night when she is sleepiest.She will defend those eggs and baby chicks as best she can and she can peck quite hard.ight around day 21, you will probably begin to hear the little peeps of baby chicks. Exciting! You may not get a good look at them for a while. They tend to stay under mama for one or two days. And remember, some will hatch and then the rest may hatch over the next two to four days.
