Hi! I have a ~9 month old Delaware hen (Bessie) who has been laying since April. She lays pretty regularly though her eggs are a bit small compared to her sister (Gertrude) which is the same age and breed. My main concern is that she often spends a majority of the day sitting in the box trying to lay. Also her comb is a bit shriveled and very pale compared to the other Delaware. She doesn't seem broody to me and never has a problem with me taking the eggs. She will just sit in the box for 6+ hours and makes a lot of noise when she lays. Once she has laid she will leave the box and roam with the rest of the flock. Anyone experienced a hen like this? Could it be some kind of vitamin/nutrient deficiency? Thanks for any help!
