I bought this Ameracauna when it is 3 days old. I bought 4 total the same day, all of them were 3 days old. 2 days later, this one was significently bigger than other 3. Unfortunately, all other 3 have gone (I think by predetors). Now the remaining one is a little over 11 weeks old. Please see the pictures. the brown/blue one is the questionable one. I can not have rooster....... Please help! Thanks.
