I would definitely get some nutri-drench.. we recently lost a Buff Orpington baby. I wish I had had that on board from the time I brought her home. We gave it to our new Buffs and they are thriving. Something we are also doing is giving the nutri-Drench as a week tea in their waterers. It is working so well. What heat source are you using? We use the MHP, it is awesome too. I have heard that if your temps get too off with heat or cold it can keep pasty butt going. Oh, I almost forgot, we also gave a hard boiled egg, ground in the food processor to the new babies who had a bit of yuck on their butts. It worked amazingly well too.
