My last hatch 3 fully developed died days 20/21. When I eggtopsied one had internally pipped but was shrink wrapped so never made more progress. One I believe had drowned because there was still quite a bit moisture. (The third I couldn't figure out.) But the one that had the excess liquid was a larger egg, large enough that he had extra room in the egg. He would roll as I rolled the egg. I think in my case having a shrinked and a drowning was due to probably the porousness of the eggs, and size. My one that pipped was a standard chicken, and the egg may have been a bit more porous, the one that drowned (and the other one was NN) was obviously because of the size and the shell was probably less porous so it had more liquid and didn't expel as fast. At least that was my determination, whether it's right or not is another thing...lolSee I thought it was shrink wrapped too but then how the heck did I get a sticky chick (to high humidity) in the same hatch as shrink wrapped chicks (to low humidity) boy I really do hate this winter. Good point as my hatches last year where may and later. Thankyou for your help and so sorry about the 1/40 hatch that had to be devastating! I hate shipped eggs alsobut was unavoidable, searched for a yr for welsumer local and nothing. Now I only had one hatch![]()
