i gave my 3 day old chicks 2 worms last night on their square of aluminum foil... they freaked out at first, terrified of the worm, backing away, and running for the corner of their brooder....
then after about 10 minutes of it trying to crawl away and into the bedding (and me repeatedly putting it back on the foil) one brave one started pecking at one. after about a half hour, they were each taking turns pecking at them... still unsure. after an hour they started going back and forth between ignoring the worms and looking at them with their heads sideways...
suddenly one grabbed the worm off of the foil... and RAN with it, peeping like the most excited chick in the world! the other chicks chased him! going "I WANT THAT THING!"
its like when a little kid picks up a toy another kid is ignoring and they start freaking out saying "HEY! I WAS PLAYING WITH THAT!!!!!!" when they really weren't.
well they realized there was still that other worm, and another chick grabbed that one. the chase was on until the chicks who grabbed the worms swallowed them whole! totally insane! i couldn't believe they could fit that whole worm in them! little bantam babies! amazing. and totally hilarious.
also, worms = pure protein!
