I have buff orpington, 2 red star, and 2 ameraucana. My ameraucanas are the only one laying unusual shape size(very large and very small thin shelled egg) and both have watery-whites; the eggs that watery whites just started this past 3 weeks. I wonder if its the cold because here in Dallas it has been very cold fluctuating between 20 f to 38 f. I am not to sure if it is safe to use the eggs that watery, so I just boiled it well done and feed it to the chicken so is not wasted. I have been feeding them high calcium & omegas mixed with their food. I think my americauna's just plain different. In the future, red star are the best egg layer. As for my buff orpington, so so. My buffy(buff orpington) just broody too much, like every 3rd week!
