Well today was a lesson learned day. A lesson that I should go back to practicing what I preach. Today the babies hatched Oct. 31 (see post from that day) started dropping dead. For the four weeks since they've hatched it's gotten down to 30s some nights and chilly every day so I had them in a pen in the coop which I cleaned regularly and had heat lamps in. They have never been allowed to free range or allowed out of pen. I just thought it was too cold and too many chicks to try and round up. Anyway, for the past two days I've noticed them becoming lethargic and huddled up under the lights. When the first few turned up dead in the mornings, I thought they got smothered under the huddle, even though I had two lights. This morning they just stared dropping dead. When I started pulling out some of the sickest looking ones, I discoverd they were skin and bones (lots of feathers hiding it since they were Cochins). I brought some of the sickest inside and they are having bloody droppings or watery diarreah. All of the chicks have patchy looking feathers and bare spots. They just look terrible.
By comparison the five babies that the mama hatched and has been raising look beautiful and they are the same age. They have been free ranging with the mama and the rest of the flock since they hatched. Have never had a light. The mama stayed with them at night for the first three weeks but went back to sleeping on roost last week so they hang out and sleep on floor of coop, with no light, or roost where they want to.
I'm fully convinced that the others have gotten a disease or worms because they have been raised inside, with heat lamps, and no fresh air or sunshine. Though the pen has been cleaned regularly, they are still in their own droppings without sunshine and fresh air or the room to really run around and fly and dirt bathe.
I don't know how many will die at this point and now they have been exposed to all the others but other than the 5 with the mama, everyone else is older so I'm hoping if it's Cocci no one else comes down with it.
I will never raise baby chicks in a pen again. Two years of doing it the more natural way and never a loss and now I've taken all these "by the book" precautions because these chicks were more "rare" and now I may lose them all. Never again.
I dumped them all out, removed the pen and am praying for the best at this point. I'll know more in the morning as to how it's all going to turn out. I left two lights in the coop, set low to the ground as well as a heater and when I last checked on them they were spread out and have been running around eating and scratching so maybe getting out of the pen will save some of the healthier ones. I have everyone on Wazine and Terramycin just in case.
Like I said, I'm going to go back to practicing what I preach. I've watched the mama hen and she took her babies outside from day one. She did sleep with them under her wings for the first three weeks but is now weening them. She hangs out with them during the day while free ranging but goes back to the roost at night. I figure mama knows best.
