I had lots of wonky pullet eggs from 5-8 week old birds on a 28% protein starter, I hardly ever have a wonky egg since switching to 21% layer feed (birds also start laying at 7 weeks instead of 5), until just recently. I have three 9 week old hens in a separate pen, 2 are celadon and lay normal eggs, the the other is a normal shell but every third day has a double yolker and has also had a soft shell. Is she going to grow out of this or are some just prone to laying weird eggs on a regular basis?
