Good Afternoon Luce,
If you are registered with a vet for your animals it is worth getting a litre bottle of Baycox to treat coccidiosis, we have lost a couple of birds but were too late administering the Baycox.Now whenever we see a bird whatever age looking lathargic we put the Baycox in their water and it has done wonders for birds who looked like they were really bad.
As you possibly know they can be fine one day and at deaths door the next, so far we have saved 3 adult hens using the above procedure, we were told that adults would have built up enough of their own immunity to coccidiosis but we have found that this is sometimes not the case, also there are many new strains which seem to effect adults as well as growers.
We now feed medicated food right up to when they get breeder pellets/layer pellets, so medicated chick crumb and medicated growers too, the brand we use down here in Somerset is C.C Moore which is reasonably priced.
We also have some VermX Organic worming pellets which is mixed with the food when they are down which seems to be really good, cider vinegar goes in the water monthly and the majority of the flock get flubavet every six months.
We have heard excellent reports of Herban and are considering getting a bottle as spare just in case the other things do not work, obviously the advantage with Herban is that it is 100 percent natural and organic.
We hope this is of help to you.
Kind Regards
Robert & Sarah.
