So I have three hens. All are around 6 months old. 2 barred rocks 1 easter egger. The barred rocks aren't laying yet. The EE has been laying for about 2 weeks. Twice she has skipped a day and then layed 2 eggs the next day, but this week she skipped 3 days and today she layed 1 egg in the morning and 2 in the afternoon, all hard shelled medium size blue green eggs. She seems pretty healthy, clean fluffy feathers around her vent & no discharge. She does look a lot smaller today than she did yesterday, but She is her usual perky self. Should I be worried?
