I had been getting medicated chick starter in small packages from my local feed store until recently and my 4 pullets (now 5 weeks old) are eating more than ever so I am almost out of my medicated starter. I went a different store this time (Tractor Supply store - and got Stall-Dri! Yippee!) and they had 50 lb bags of 24% starter, or 25 lb bags of 20% starter/grower - and since I've read that food loses nutrition over time and that I should buy smaller amounts, I bought the 20 lb bag of Dumor 20% protein starter/grower. Now that I'm home I'm realizing that is is not medicated, and my chicks are only 5 weeks and I read conflicting things about their need for medicated food. They do still have runny poops from time to time and I would hate for them to get coccidosis. Since they are a small flock (4) and not around other chickens, is it okay to shirt them to unmedicated feed? Also, the starter feed has different % of protein for different brands - so my switch to Dumor is a slightly higher protein % than I was using before. Is that switch okay?
