I have my chicvs outdoors in the mini coop they are almost 4 weeks old and have the ecoglow for heat if needed. I open the front door of the coop and put netting up so they can't get out but they can look around and get used to the enviroment. I was outside when I noticed a bluejay swoop down and try to get into the mini coop! Thank goodness for netting! Will a bluejay hurt the Chicks? I have my main run and coop completely covered with deer netting, it's better than the regular bird netting, stronger and lasts longer.
