Not necessarily smaller and slower is a meal! As i was sitting in the run visiting my flock today (8 weeks old almost) a number came running past me to the wire all of the run, I turned and saw a decent size black flying beatle with two red spots on its back and red on the end of its antenna. I have never seen anything like it, 6 came at different times when they saw the movement and jumped up to get it, took a look at it and went the other way! lol They could have easily gotten it, I have seen them eat beatles. They all said no way, I gotta admit I thought he looked scarey to! I have tried to find it by googling different ways and I cant find anything that looks like it. I live in Nebraska Panhandle, anyone have any idea what this thing might have been? Hard looking shell, but had wings, shiney. Red on back and end of Antenna.
Mine are sometimes afraid of bugs when they're that young. They'll grow out of it. It is entertaining to see the chickens and ducks chasing after bugs.
Try whatsthatbug.com. I identified many insects from that site. If your girls did not eat it they probably know better, it could be toxic.
