As far as I know they're EEs, so anything could be in there. I have three chipmunks now, and the blonde and brunette, so five fuzzybutts total. I was hoping for one more, but that egg didn't make it.
What makes you think they're female? It would be interesting to follow them and see if the Legbar traits hold true.
Now, who is going to Shawnee this weekend? Shelbydog and I may be there, and it would be great to meet everybody! Cathie Sue, are you going?
Legbars and a few others are autosexing at hatch, but that only works if the chicks are pure, any crossing and all bets are off.
