I have a broody on 3 eggs and I am FREAKED about giving them vaccinations. Whete do I get them? Can I get just enough for 3 chicks and no more? what is the risk of injuring them while giving them the shot? how many/what kinds do I need? Does it hurt the poor little fuzzbuts? Can I pay someone to do it for me? How much would it cost? How DO you give them the shot? GAAAA HELP ME!!!
