I just bought these 2 chicks from a lady that was over whelmed on her property with to many birds. She has mostly silkies running around and a cochin rooster or 2. She says they are a mix of the 2 breeds. She said she had no clue on ages but guess the little one is 2 months and the other is 4 months. I wanted to get your opinion?? I know we cant really guess on sex yet, epecially cause my pic doesnt have great lighting. Thank you.
