I have 200 broilers to treat... they are 4 weeks old. I can only get the injectable is this possible to do 200 chickens like this? Is there a way to make up a water soulution that they can drink with this? How many days do I have to inject 200 birds with meds? OMG.... this is going to suck!! HELP... LOL.... Sigh.... Can I put the meds down their throat or do I have to inject them? I'm off to TSC to get the Tylan 50 right now.... hopefully I have the right stuff.
