Hello, New to this blog thing, but I' desperate! I traded in my reds after 3 years. I've always purchased pullets (+/- 12 weeks) but wanted to try Barred Rocks this time so I ended up having to purchase 3 week old chicks. Well their now 5 weeks old and I just moved them out to the cleaned up coop and I day 4 I found a large black snake had killed one of the chicks and was in the middle of attempting to eat her! I've moved the chicks back to the shed, the question is: When can I safely put them back out? Thanks for the help.
