WebShell strength is influenced by two factors. Firstly, the hen's diet, particularly its calcium, phosphorus, manganese and vitamin D intake. Secondly, egg size, which increases as the hen ages while the mass of shell material that covers cover it stays fixed. Hence the shell is thinner on larger eggs. WebJan 28, 2014 · Shell Strength. Shell strength was determined on the same shells used for the morphometric measurements (n = 18 per treatment) by measuring the maximum load that each shell valve could endure, and by measuring shell extension properties. Individual load and extension values were calculated as the mean of the two valves for each mussel. everyairport everywhere
