I hatched out some Salmon Faverolles chicks and of course its looking like mostly males. I was at our county fair and decided to buy some nice quality pullets to offer pairs with my cockerels. I plan on keeping them seperated for a month, treating with Eprinex for mites/lice/worms. I need to find out if they have been on medicated feed as we have had Cocci in the past and my flock is clean now but concerned if its still around on the ground. The pullets are 5.5 months old-since my flock is currently on medicated feed, if I put them on medicated feed during quarintine period will these give them some immunity if they haven't been on it in the past? Any other advise on quarantine?
