I always feed medicated feed to my chicks. One time I had a whole, ginormous brooder full of chicks for longer than 8 weeks, because I didn't have their grow-out coop & pen ready for them at that time. Stupidly, I changed them over to non-medicated feed because that is the time I always did it..... but the chicks stayed in that brooder for another 3 weeks.
Within a week of hitting the ground, they got SICK. Within 3 days I had lost 10 of them. I had to treat the whole flock with Corrid V in their water (and now keep that stuff on hand!!!!) The adults were all fine, and so were most of the other younger birds, but that batch o' chicks all got sick. If I'd had any sense at all, I would have realized the Amprolium was well out of their system and therefore could not help them build resistance to the cocci in the flock or on the ground. It rained right about that time and the whole compound was mucky for several days.
I now make an effort to feed the youngsters with medicated feed for at least 3 weeks past the time I put them out in their grow-out quarters.
