I have a several different types of chickens of varing age groups. In the middle age group 3 of the 4 have been laying for awhile now. Yesterday 2 of the eggs were soft when laid. There was also the regular 3 eggs in the nest. Today my Barred Rock (whom I believe has not been laying, though I've seen her in next boxes before) has been in the nest box twice, scratching and apparently trying to lay an egg but hasn't. Is this normal for a new layer?
