Hi there, this is our first time here on this form, so many thanks in advance. We're first time chicken farmers with a collection of 8 Dominique chickens that are 21 days old today. We purchased them from a semi-local farmer, and we know that they weren't vaccinated against any diseases. One of them has stopped eating, drinking and being active. There seems to be no signs of outside injuries or other indicators of disease. Our friends kid gave him a ride around the house in a Tonka dump truck 2 days ago. He hasn't really been the same since. It was less than 5 minutes, and my wife is convinced that he is just "stressed out". We did just go from paper towels to pine shavings the day prior for their bedding. Theyre on chick starter feed, have plenty of clean water and a heat lamp. Does anyone have any suggestions? Thanks!
