Here is my pool brooder. I wired chicken wire around it which has kept them in so far. I have 11 chicks which are 3 1/2 weeks old now. I have laid a piece of wire across the top too as they are jumping quite a bit. This is my first time. They are fun to watch grow.
Maybe the chick is bored? Maybe something else in the brooder might help like a small mirror or a clock? To the person who said their chick was pecking out morse code night and day.
The bales sound like a good idea once I move them into our carriage house. I was trying to figure out how to enclose only one quarter of the building for them without going into a major construction job of building walls.
