I have this 4 week old rooster that has torn tail feathers off 4 chicks that has left them with bloody bums.. I have separated the roo from the rest. The 4 chicks I put in another cage for their protection. There where no outlets within miles that I could buy hot peck solution. I mailed ordered some from Meyer. Once treated with the hot peck solution how soon can I reintroduce the chicks back to the large brooder? John
