I believe that they are pure bred...at that time i had my seb and pil running together. but i believe this group of four at out of my seb goose en and my two seb ganders due that there top gooses.
Anyone got ether Pilgrim baby pics or Pil x Seb cross pictures??????
most of the time geese make peep holes around 24 hours after air sac "envasion". i know a few make holes with bits and needles, as i did with my call duck eggs back when i raise call ducks. the first four did it all on their own. but i'll see how the rest go with mine. Hope that helps somewhat
