Abstract
Record of an egg probably held for several weeks in the oviduct of a 4-yr.-old hen of Barred Plymouth Rock and Rhode Island Red derivation. The normal egg shell was covered by a layer of protoporphyrin, the pigment normal to brown-colored eggs; shell deposition had seemingly been regular and then stopped, but protoporphyrin deposition had continued.This publication has 2 references indexed in Scilit:
