Should I vaccinate and medicate new chicks under broody

[PastyButtsMom]

Mama hen could possibly have been exposed.

Yes, I hatched 2 Mille Fleur d'Uccle chicks in April and they live in a separate run than my 3 vaccinated hens (2 Red Stars and a RIR), but the hens will frequently come lay next to the run in the sun. So yes, I have successfully raised the unvaccinated chicks around the adults. I didn't put the chicks outside until they were like 9-10 weeks old, because we kept going on trips and it was simpler for the pet sitter when they were in an indoor brooder.

I had no problems with egg yolk with the chicks, and I hope it'll stay that way!

If I were you, I'd feed medicated feed. I didn't, because I try to raise a flock without synthetic materials as much as possible (I ALWAYS use a chemical dewormer, though), but in your situation I would.

Thank you and I agree that since yours were inside, I'm sure their exposure to coccidiosis was minimal, if that and my chicks are being raised outside with Mama. Thank you for the resource - I will check it out!
