My girls have started laying 2 1/2 weeks ago. 6 out of my 11 hens are laying. All 19 wks. with the exception of 4 being approx. 22 wks (Isa Browns). I've noticed that some of the egg whites are partially runny like water. The yokes are a nice deep color. With some, the eggs whites are thick surrounding the yoke and then tend to spread out & be runny like water. Is this because they are just starting to lay? Will this improve with age? They are not old eggs, they are picked up daily at various times and refrigerated. Is it my refrigeration temp? Am I placing them in the refrigerator too soon? Older posts addressed the similar question but didn't actually answer it. One mentioned Infectious Bronchitis and I had a flash of panic. My girls are healthy, eat grain, scratch, veggies, get dairy treats, grit, oyster shells and free range 2-5hrs. daily. None appear ill. Their shells are nice & thick. Suggestions & opinions are greatly appreciated.
