Hi, I was in a pet store today and to my surprise they had chicks. They had some Polish which I have always wanted and so naturally I couldn't resist. However I have no idea how old they are and neither did the person working there. I have only ever had silkies so I'm not very familiar with the sizes of a standard chicken. I would like to know roughly how old they are so I can figure out when they can go outside. Also, is this a breed that you have to wait until someone crows to figure out sex, or are there any early indicators? Thanks for any info! Here is a pic of one of them, I got three, they are all roughly the same size.
