Explain the logic of this to me

No I did not put these chicks in this bucket before anyone gets mad, there's about 30 of them in this 5 gallon bucket.. I was feeding and there was grain in the bucket that I was going to pour into their feeder, my goat got out so I set the bucket down without pouring it to them because I didn't want my goat to go and Destroy something (he's a billy goat and likes to head butt shiny things like my car) takes me about 10 maybe 15 minutes to get everything back to the way it should be since he broke the fence, I come back and I guess they thought they were starving because all of them minus one were piled into the bucket on top of each other... I have absolutely no words
