Okay riddle me this-I have a broodie who I set on 6 eggs 3 weeks ago. I candled them at 7 days and only had one starter so I pulled the other 5. Candled again at 14 days and had good development. I bought 6 day old chicks Thursday to graft to the hen Friday night after the lone chick hatched which went beautifully. This morning I went to go check on everyone and there are not 7 chicks like I expected but 9!! There was only one shell in the nest and 5 yellow chicks, 3 with feathered feet (my rooster is a conchin x leghorn) while the chicks I bought were EE and CornishX. How is this possible?!? Three yolked egg? But wouldn't it have failed due to too little space?!? The three are obviously from my rooster as the feet feathering seems to be a very dominate trait, but I can't comprehend triplet chicks!!
Anyon else experience this phenomenon?
