We got the three hens around November, and we think they were all 5 months old; Goldie started laying first, followed by the other two. They were all steady at around 5 eggs per week; Goldies eggs were larger than the other two girls eggs. Goldie laid eggs on Jan 2nd, 3rd and 4th, and then came to a screeching halt. On the 6th we did get one egg that I'm pretty sure was hers, whiter than usual with some calcium deposits on it. The other two have continued laying at least five eggs a week. We were thinking maybe she is older and not a pullet, and that was why she wasn't laying in the winter. For a month she didn't lay a single egg until today, although she sometimes sits in her nest. Today she was in her nest for a while, and then I found this soft egg. (next to an egg from today from one of our others). Note the straw and stuff stuck to the egg is just from the bedding in the nest. She is happy, active, good appetite, runs around and all three socialize very well with each other and with our rooster. Nothing abnormal about her other than this. She definitely eats as well as the other two. I know this is common when they first start laying, or if they are calcium deficient, but she laid steadily from late November to early January. Is it normal, or is it anything to be concerned about?
