I have an Ancona hen and for the last maybe 3 weeks there has not been any white eggs, I have looked all around the coop and the whole yard and garden and there has been no sign of those eggs. She has been acting completely normal except that her comb is straight up and is used to be flopped to the side. I believe she has been laying since she was 23 weeks old and now she is about 9 months old. All the other hens are brown layers if that helps. I do know she is not molting. She flies out of the coop all of the time so it is very likely she would laying somewhere in the garden or yard, but as I have said I looked everywhere, and considering that I have not seen a egg from her for 3 weeks I would think that if she had a batch of eggs somewhere that they would be easy to spot. So if anyone has any ideas that would be great.
