HI, My 2year old Rhode Island Reds are acting a bit strange. For about 3 weeks Ladybird has laid eggs only sporadically and has sometimes laid some really weird "soft" eggs. Millie is laying smaller eggs than normal, and they are starting to look chalky, which is how Ladybird's looked before she pretty much stopped laying. Is there some dietary change I should make? They are eating a chicken feed that they have had before, and some kitchen scraps.
