My 18-week-old Speckled Sussex, Mildred, I THINK laid her first egg 4 days ago. But she hasn't laid anything since then. Is that normal? The egg she laid was a large egg, cream colored with a slight pinkish tint. It was as big as those of our 2-year-old Welsumer, Nellie. Since Mildred hasn't produced anything else yet, though she has gotten very noisy with bawk-bawking around the yard and squatting when I put my hand near her back, I'm wondering if it was not her egg I found in one of the nest boxes. Is it possible that this egg could have come from my Welsumer and just not received its usual coat of dark brown for some reason or other? The Welsumer didn't lay anything that day (she usually produces an egg every other day), unless this odd colored egg is hers. Still waiting for my 2 Wyandottes to produce. They're the same age as Mildred. I understand they may take longer to mature. But their combs and wattles are getting redder, so I think we're close. I appreciate any comments to solve my mystery. (I told my daughter I might go install a spy-cam in the coop just to know who's laying! Kidding about that, but if I had the money to splurge, I'd probably do it.
