Hi, This is my first post on this forum...so Hi everyone from Sydney, Australia! I have four ISA BROWN hens, and they have been laying now for a month...well most of them there appears to be one slacker! We normally get three eggs a day atm, but every now and then we get a big dinosaur egg and one other regular egg. This has happened twice now. The big eggs are 85g and yeaterday the egg was 86grams. The first time we had a big egg we all crossed our legs and thought "ouch!"........ but thought it was a one off. However the egg yesterday was even bigger and even had blood on it.....which is making me really concerned. Our regular size eggs are 67-69grams. Can anyone tell me how or if the size of eggs is influenced by things like diet? ( they have been breaking into my worm farm and feasting, and I thought perhaps the high protien could increase the egg size?) Are free range eggs normally bigger? And should I be worried about the blood on the egg, and be getting treatment for my chook if there is blood on an egg of this size?
