It seems the medicated feed is mainly to prevent coccidia.
My options for sexed birds locally are TSC and 2 other feed stores.
There is a farm near me that sells at the chicken swap out or local feed store (that doesn't sell anything but feed), but she doesn't sex, so unless it is a breed you can visually sex, you get what you get.
There used to also be a semi feed store/chicken place - he used to hatch a bunch. I'm not sure if he sexes or not, but what I've seen in the crapton of eggs in the brooder, but they are mixed (he knows what the eggs are going in, but once hatched... they are all together - maybe he knows what is in there well enough to know what is what).
Right now, my plan is obtaining locally rather than ship since I really only want 2.
The 3 feed stores would be chicks from a hatchery.
The farm and the other guy would be their eggs hatched locally.
Chick days brings a run on chick starter, so I figured I'd grab some soon while I still have a selection.
So medicated or not?
