Ok, we have for a couple of weeks now been getting this very large Jumbo egg that is hard, but all wrinkled up. I don't have any pics to show unfortunately. I probably won't after tonight. Every time we have gotten this crazy egg (probably three times a week) it has been a double yolk. Now we get doubles from a leghorn now and again, but never this large and never wrinkled. Well, this morning I noticed one of my Buff Orpingtons was just not herself. She looked very cold and it has been cold - down to 39 last night - for south Texas. Well, I put her in a nest box and moved the heat lamp near her and went about preparing for company. Tonight I go to check on her and she is a limp wash rag. She tries to eat and drink, but it is like something has sucked the life right out of her. No other illness signs either - except in the nest box she was in - no other chicken had any way of getting to as I locked her in that section of the coop - was another one of the jumbo wrinkled eggs. So my question is, if she is laying these enormous eggs, can it do damage to her internally and actually be what is making her so weak? She is a hatchery bird, so I know she is bred more for performance then correctness. Any one else had this happen to them with hatchery stock?
