We have 19 three week old chicks. The weather is getting warmer here in Texas. The chicks seem awefully crowded in the 2'-4' brooder. Im thinking of moving them to the run and coup. Your advice? I put hay on the floor of the run and coup. Is that a good idea? It seems like an awefully fluffy cloud that would be hard for the chicks to get around on. We are newbees and just want to make sure this is the right move.
