My 10 hens have laid about 4 medium sized eggs a day for the last 5 weeks since I got them. The New Hampshire Red eggs have been the largest and the speckled sussex and partridge rocks have been the smallest. My lone EE hen has been right in the middle. But over the past 4 days, I've been getting Speckled Sussex eggs that are WAY larger than large store bought eggs. Is there an explanation for this? Would it have anything to do with the weather warming up? Just curious, I hope they keep it up.
