In Europe they actually let the egg whites sit out without refrigeration for days so the water evaporates and you have more protein for the amount of liquid. I do not actually recommend this, but your 3 day old refrigerated whites are definitely still good.Source(s):n Europe they actually let the egg whites sit out without refrigeration for days so the water evaporates and you have more protein for the amount of liquid.

It means all the babies hatch close to the same time. Mother robins may start incubating their eggs during the evening after the second egg is laid, or after all the eggs are laid. They sit on the eggs for 12 to 14 days.ost birds lay their eggs at sunrise, but NOT robins! They lay their eggs at mid-morning. That's several hours later than most birds lay eggs. For robins, this makes good sense.
Ermine mate in late spring to early summer. Females are polyestrous, but produce only 1 litter per year. Young are born in April or May after an average gestation period of 280 days, which includes an 8-9 month period of developmental delay. Longer days beginning in March trigger the resumption of fetal development.
