I have 13, 5 month old pullets (Araucanas and RIR's) and most of my eggs have been standard pullet sized (smaller than a medium egg) but here and there I get these enormus x-Large eggs. What does this? I'm hoping its just happy chickens!! For the past few days one RIR has given me 3 of these huge eggs. My Araucana (Laya) gave me one and that was after a night in the chicken hospital for some R&R from the roo's and to wash her saddle and doctor up roo wounds on her back. Just wondering what cause this. Thanks in advance, I'll post a few pics of the eggs in a few mins.
