I had four little chicks around the first of may, two americanas and two golden laced wyandottes. I had read before & had done with my previous two chicks to give them a little dirt from our yard to build coccidiosis immunity. I gave some dirt to these chicks as well (although I didnt do it until this batch was older maybe 4-5 weeks) and suddenly found bloody stool in their little space. Id never had this with my previous two batches of chicks. I googled it and realized it must be cocciodisis. I gave them corid and thank The Lord they quickly improved! At 6 weeks we gave the two americanas to a friend and they said they did great on their farm! I waited a little longer for our two golden laced wyandottes because they seemed a little smaller & younger than the americanas. I put them out and noticed them eating SO much dirt it worried me. 5 days later they seemed lethargic and sadly it didn't hit me that it could be coccciosis again. I lost one of the golden laced wyandottes that day I think the coccciosis plus the heat that day even though they had shade and water was too much. One little golden laced pullet survived. I gave her corid and she got better so Im quite certain it was coccidiosis again that got her sister. Ive been afraid to take her off corid sometimes just giving her tiny doses in her water but recently took her off altogether and sure enough she got sick again Same symptoms and her poop was reddish so afraid there was blood. Poor thing took some corid orally from a dropper last night and is so much better this morning!! I just am worried as she is coming up on 3 months and seems to have no immunity to coccidiosis. My other hens (all barred rock) do great and don’t have this problem at all! Could her immunity be messed up from having coccidiosis as a chick? What can I do to help? Im afraid giving her corid so much will lead to vitamin b1 defeciency, I have given her lots of nutridrench. Any advice would be so great appreciated thank you!!
