Yes it sounds like a weasel! They can get in though very small cracks so make sure the house is completely sealed up. I suppose a rat could do the same thing.
I hope your right because I'm very attached to her already! My little one is very sketch too, the larger one is really friendly and will get in my lap. Five of my 10 birds will get in my lap and two will actually lay down and stay for awhile with some petting.
Update. Here is a picture of both Easter Eggers. I believe you are correct on that point. Notice these two, the size difference, both 7 weeks old in the picture. Today I noticed on the larger one a tiny bump on each leg near the feet. Does this indecate it is a rooster? Thanks for your imput.
I puchased two Ameraucana Pullets? I've read that an Ameraucana has blue legs although my two appear to be green? They are both different sizes so I think this one is a male. What is your opinion, Male or Female?
Thank you for the help.
