For the past few days one of my hens (a seabright banty is my smallest) has been laying TINY eggs (about penny to nickle size). These eggs are never in the nest box, always just randomly around the run. I boiled them up out of curiosity and they have a yolk section but, it is white like the rest of the egg. It does have a yolky texture though. The inner membrane on these eggs is also VERY thick. Any thoughts? Are these the "fart eggs" that I have read about? I was under the impression that those were sort of rare... My other hens are laying wonderfully normal eggs. Thanks so much for your wonderful help!
