Our hens have been laying for about 5 weeks now. The eggs are still pretty small. Average size about 43 grams. Our largest egg to date is 73 grams. Our Concern: When we hard boil our eggs we cannot peel them. The membrane under the shell will not release easily from the white of the egg. So we end up tearing the eggs up when we peel them. We have tried peeling them hot and cold. Any solutions please.
