You are going to love chicken motherhood. I personnaly use wood chip for my coop and nesting boxes make sure to clean it often or they could get mites wich are hard to get rid of. For water use anything realy it depends in winter I use something that won't freeze but in summer I use a large tin...
I have two rooster chicks when will they start crowing and will they fight often? I had a rooster but the ones I have now are growing very fast and they are the same size as their bantam mother at three weeks they are not aggressive but will they be once they grow older
