Bad news, folks. Do you remember Mystique, the gorgeous partridge NN, large good body, some Fm-ish traits? Was certain I would breed her. And Trinity, the other bigger NN girl, all black, NN phenotype? Her too. The two I was certain to want to breed.

Well, as I was trying to nail down the egg eater earlier (problem fixed now), I noted that SOMEONE is laying a lot of these (below), and I'm afraid it's got to be either Mystique or Trinity (I think it's Mystique). Not good for breeding plans...![]()

Anyone ever try that food coloring on the vent thing to tell who's laying what? I need to know for sure, and it's rare that I can just hang out and watch all 7 girls go in and out of the nest boxes during the day (even on a weekend).

Do you track egg weights? I've found this VERY helpful, especially when they first start laying. Not only has it helped me determine when the eggs are sizable enough to ensure a good hatch rate, but noticing a sudden increase in egg weight, not just size, has helped clue me in to the probability of a double-yolker so I don't need to candle every single egg. @hellbender hit the nail on the head with this one....DYs are not uncommon in pullets that have just started laying. Most of my DY girls have leveled out after about 2-3 months of consistent laying. Now their jumbo eggs typically have one massive silver dollar sized yolk instead.
