5 week old chicks. After their first day outside in the run most of them have similar nose wounds. I don’t know if it’s from pecking at the ground for the first time or trying to get through the hardware cloth. Hardware cloth is not a new concept to them though. What should I do? Should I put them back in the house until they heal up (to keep dirt out of the wounds)? or should I put some sort of disinfectant on them? I’m worried.
