Hey guys. I bought some chicks from Ideal Poultry. They semt me my chicks and 12 others as packing peanuts. Over in the what breed am I forum, they think the 12 are SLW's. We are trying to figure out when to butcher them. THey are about 6 weeks old now and have been fed Purina Medicated start and grow. Do I need to switch thier feed? And when do you think would be best to serve them up to the freezer?
