Oh boy, I though they were under 2!How old do they need to be? They turn 4 in November. If she continues to avoid egg eating Flurry will get her chance as well if she chooses to go broody. She will soon enough. She spent over half of last summer broody but eating every egg she came across. Like Gryffyn when the time comes she will be given 4 egg the first time around. If Gryffyn does well with these chicks next time around that big fluffy booty is getting at least 12. Honestly, she is big enough I could easily stuff about 16 under her and she would have no problem covering them all. Flurry while smaller could handle a dozen herself.
