Hi, I'm new to raising of chicks but since I'm studying Animal Breeding and Genetics in the University, I feel I should try putting some things I've learnt to practice. So far I'd say I've failed woefully. Here is my story. I received my DOCs (broilers) on 15th of October 2015. I ordered for 50, one died even before I got home or from the hatchery (who knows). I made a sugar solution and dipped their beak in the water and they all drank. I put them in their brooder with moderate temperature. I know the temperature is moderate cuz they were moving around healthily, some eating, some drinking, some resting. The next day, I put anti-biotics in their drinking water for 3 consecutive days. Everything went on fine until Day 4 I woke up to see one of the chicks dead. I removed the dead chick and threw it away and cleaned their brooder. Another chick died on day 5, 4 died on day 6, 2 on Day 7. I got really angry and suspected it could be coccidiosis cuz some of the chicks were listless, no appetite and saw blood in their poop. I started using Amprolium + drinking water on Day 7. 2 more died on day 8. I decided to clean and disinfect the entire brooder on Day 9, but 2 died on day 9 but I think its not as a result of a disease, I think they trampled on them. I used amprolium from day 7-10. One died on day 10 which is 25/10/2015, another on day 11 and another one today (day 12) 27/10/2015. So I decided to introduce Gumboro Vaccine today. Although deaths between day 10-12 were more like trampling and not disease related (I think). The mortality is just too much, I feel like I'm the most terrible farmer ever. What did I do wrong? Could Rats be killing them? Help me please. Thanks.
