One of my BOs just started laying this week and of the four eggs she's laid (that we know of) 3 of them have been rubber eggs. The first had no shell at all and broke and the other two have had a very very thin shell. I'm almost positive that she laid at least one good egg -- we got five eggs from 5 layers the other day so one of them had to be hers. She's 22 weeks, has been on layer feed for 3 weeks, and we added oyster shells this week. I also started giving them yogurt. All of the others are laying perfect eggs. If this keeps happening, at what point do we consider it a "problem"?
Don't worry. It can take a couple weeks for them to get it right. The extra calcium you are giving should have her cleared up in a week or two.
Only a problem if it goes on for a week or more. . . It is natural for a new layer to have glitches in her eggs. I don't even supplement extra calcium and I have tough as nails egg shells.
I have two BO and one of them, and one of my other breeds had this problem. It sorted itself out in a few weeks time. I do like to give extra calcium....just cause I like a good hard egg shell and I can't seem to get that without supplimenting it.
I have a almost 2 year old hen and she is still laying me Rubber eggs. Well at least when fluff feels like laying an egg
