Can anyone tell how old this silkie may be? I was told he/she was a week old when I go it which would make it 5 weeks old now. The large buff/blue orph is supposed to be 7 weeks as is the black sex link but as you can see the buff/blue orph is a lot bigger s I am having trouble knowing their true ages. I would like to keep them outside full time but not sure if the silkie is big enough. It gets as low as 60 at night right now but 80+ during the day..... any advice?
