Our 20 week old White Rocks (9) are beginning to lay (well 6 of the 9 so far) and we have 1 (we think just one) that we have found her eggs are always a very soft shell. The first two times the eggs were torn (?) open and I cleaned up the mess but my wife said she collected one today that was soft but whole. All the others seem to be doing ok; their shells are fine. We feed them oyster shell with the scratch but not always with the laying mash (crumbles). Do we need to be doing something different? Do you think it is just one of our girls might have some sort of 'issue'?
Thanks.
Thanks.
