I did have a batch of Ameracaunas that were all clear and shipper said she has 100% development on site. I wonder if some hubs are harder on eggs than others.I hate that I can't remember this (I'm sure I've asked you several times before) but are your Polish large fowl?
Congratulations on such great hatching success! I'm having a hatching issue right now, 1/2 are shipped but only one has even pipped and they were due yesterday....anyway, the pipped one was not shipped.....
My polish are LF
