I ordered thirty of them knowing that the cold of the season was probably going to kill a few. Five were dead on arrival and two died shortly thereafter, I have already called and had them credited back to me. When I received the birds I put them in my kitchen(eventually to an outdoor heated and insulated brooder) in one of those metal water troughs and put sawdust on the bottom. I place a heat lamp in there and some water with chick starter. The birds are not too hot and seem to do really well, move around, eat, and are evenly spaced etc. Then seemingly out of the blue, one will be sleep more and not move as much and not look as healthy as the others, this usually happens to one or two birds at a time, then within a day or two the bird is dead. I have lost nine total and this is how it happens. When the birds start to look sick, I have put an antibiotic in the water, which is cleaned every twelve hours and replaced every twenty four hours, and follow the instructions on the package and only use it for the first two weeks. I also keep the litter pretty clean and replace it every couple of days and lay fresh two or three inches in there. I have ordered poultry from other hatcheries and have had similar results as I am currently having and have come to the conclusion that it must be me. Please tell me what I am doing wrong. Last year I ordered 35 from another hatchery and lost all but five, ordered a second time of 25 and lost three that time,I also used the antibiotic, but the same way I am loosing the birds I have now. Is it something that I am doing or do chicks just die sometimes? The odds seem to be against me. Any help would be greatly appreciated as I want to raise chickens multiple times a year.
