So I was doling out the minnows about 4 per day to the chickens. The first two feedings went well. The third was OK, by the fourth day there was very little interest. We couldn’t even get our cats interested in the wiggly things. So we ended up bringing the last four back to the tank. (I promised my youngest she could keep two of the minnows.) All that activity was too much for two of the fish, and they passed on, but my youngest now has four pink minnows in a pink tank. She is thrilled!
