Corid, only to treat babies 2-8 weeks or give to laying hens as well?

[KMSonthecoast]

SO I have 4 adult hens. Three are currently laying (one is older).

I picked up some chicks from 2-5 weeks and I was given a pair of bantams about 8 weeks.

The new ones are kept separately in a run adjacent to the hen house.

The hens free range and stay in the hen house at night, but do not go in the run with the young ones.

I found bloody stool in one 5 week hens poo and maybe some in one of the 8 week bantams poo. It seems like cocidosis (sp?).

My local feed store said it is common out here and the Corid should work. It has been a week the young one have been on Corid and the one 5 week chick I know had symptoms seems fine and the others seem fine.

I did not treat my 4 older hens. I see no bloody poo in the older hens. They some nights have watery poo, I find in the morning, but they eat a wide variety of plants and scraps.

Q 1) Should I treat the older hens or are they likely immune? If, I treat them do I toss the eggs or are they ok while on Corid?

Q 2) Do I give a vitamin supplement to the chicks after the Corid dose or should nutrena/purina chick starter be enough?

The older hens have built up their immune systems and can handle coccidious bugs, no treatment necessary. Giving them a vitamin boost should help them recover, but if they are eating well they should get well with out the extra. The runny poop is normal they have pockets in the intestines that empty periodically, that causes it.
