I know I'm supposed to hold my chicks so they get to know me, but every time I go up to their brooder they run around and start peeping.... Bothered I am there. They're running from me now when I try to catch them and they're trying to jump out of their brooder. I put a screen on to keep them in. Is this normal behavior?!? Should I keep trying to hold them or am I just stressing them out?! They're almost 2 weeks old. 2 production red and 2 Plymouth Barred Rock.
