Looks like the chicks are 5 weeks old. Let them outside but still have heat lamp for at night temperatures. Watch out for hawks and ravens when outside.Keep them warm until about 10 weeks old. just my opinions. Have the feed and water inside so they go back in at night.
Thank you. Seems like an interesting site. Someone on craig list just posted chicks for sale. Go to Michigan and click for upper peninsula. at Rudyard.
stumbled upon the site while searching about turkey vultures. I grew up on the farm and also owned the feed mill for 12 years so if I can help out someone on a question go ahead and ask.
