Our son has a few egg layers that have been laying all season.He is now getting an egg from 1 of the hens that is very poor quality.The shell is thin,the yolk Breaks when egg is cracked into a pan and the white is runny. Does anyone know if this is a sign of disease or of poor nutritional values?I suggested Oyster shell For thin egg shell But I'm not familiar with What could be causing the other 2 things.Any help is appreciated
Older hens will sometimes lay poor quality eggs. Without knowing the age of the hen or what kind of diet she has been receiving, it is hard to get a handle on the cause. Bronchitis earlier in life will sometimes cause hens to lay eggs that are misshapen and/or of reduced quality. Here is a link to a veterinary description of various conditions causing eggs the way you described. Check out the one on "egg yolk peritonitis" and any others you suspect could be the cause.
