I recently got 4 baby chicks from a hatchery. One Sussex, one frizzle, one polish, and one Americana. I was told they were a week old, except the Sussex was 2. Brought them home, put them in a 40 gallon plastic tub from TS, feeding them chick starter, and electrolytes, lamp at 90ish, pine shavings. Been cleaning tank every other day. On day two, the temp raised to 93 for less then an hour, raised lamp, went back to 90 that night the Sussex died. Then the Ameraucana started being less active and had eyes closed almost all the time, while eating, all the time. Went back to hatchery, bought 3 more two Sussex, and a polish frizzle. Ameraucana was significantly smaller then all the rest, got trampled, and died the next day. Have them on Corid now, today is 3rd day. Now one of the Sussex is, fluffing up, keeping eyes closed and not as active. They are all 2 and 3 weeks now, have temp at 85ish. I don't know what I am doing to kill these poor birds. They are not vaccinated. I feel like this other Sussex is going down Hill quick. It was sneezing when we got it a little. But was active and eating and drinking. Now this morning, just staying in the corner, fluffed, eyes closed. What can it be, and what can I do? I made it a egg yoke scrambled, with a couple drops of electrolytes, and sprinkled with cinnamon, but can get it to eat at this point. Have put beak next to water and corid, it will drink, but I feel horrible, cause I don't want to lose another baby. Please help me. Thanks!!
