My first timer araucana hen was sitting in 8 Rhode island red chick eggs. so far she crushed one at 10 days and now we have 7. so far 3 hatched and one was nearly killed by other hen. 5th one hatched today, after i had to care for it my self, as the mother crushed that one too, so the sack wasent fully drawn in, but it was nessary to get it out of the shell. so number 5 has a plaster covering the rest of her sack, shes doing good, only the stupid mum keeps being rough. now she has crushed annother un ready shell and the chick is stuck, not ready to hatch, and another egg still has a cheeping chick inside it. day 23 will keep you posted. help need on determining the gender of these, will love both male and female. thanks!!
