Wednesday 4/3 our ring neck chicks from Murray McMurray came and we put them in the brooder which is a 2’ x6’ x 2’ tall stock tank in our garage. It is lined with news paper now and is sitting on insulated pads not directly on the concrete we have chick booster in their water which is our well water. We are feeding purina game bird starter 30% unmedicated. We are using a 250w red heat lamp and the chicks are not piling under it so it plenty warm for them. Since Wednesday we have lost 10 chicks no real signs of illness just like they go to sleep and never come back. They live a little while but just get weaker and weaker until death. Not sure what is wrong we have brooded many chicks and ducks over the years and have never had issues like this. Hopefully someone here has seen this and can help us out . We live about an hour from any town that has farm and ranch supplies but am willing to go there and get anything we need,it currently snowing here but roads are fine.
