Can you post some photos of the chicks, their poop and your brooder set-up?
Coccodia are protozoa and there are nine strains only 2 strains if I remember correctly cause blood in the stool, so you can't always go by that.
They have never been outside? Where did the lice come from?
I would re-treat them with Corid at the correct dosage of 1 1/2 teaspoons Corid powder or 2 teaspoons of 9.6% Corid liquid per gallon of water.
Give for 5-7 days - make sure this is the ONLY water available during that time period. Mix a fresh batch at least once a day.
For the chick that is in the worst shape - I would get her hydrated. Give her sugar water, electrolytes or whatever you have.
Have you been giving them any treats at all? Do they have grit?
If you still saw lice on one, then get rid of the bedding and treat the housing/chicks.
At 6 weeks old - they should really be fully feathered and not need much supplemental heat - do you think they could have overheated?
Yes! I'll post photos in just a moment.
Well, I've gotten chicks 3 times. The first time, the only ones I've had trouble with, are from the first batch. In the first batch I got 6. They were in a garage and could have had the lice from the time I got them but I think the lice came about a week later when I added 2 to the group. Those came from an outside brooder. It's my only guess because I don't think they had lice from the start. After I lost the EE, I added 2 that came from a local feed store and they do not have any lice and they seem perfect, they are crated separately right now. They are inside the house with one from the first batch that was getting picked on. She is not thriving. She is having growth and eye issues but that's a whole different story.
I lost my chick early this morning. I tried adding vit b to her water last night but she was too sick. I squirted nutridrench in her mouth last night, she was separated, I don't know, but she didn't make it.
I had been giving them electrolytes off and on this whole time but decided to stop because I read it can give them the runs.
They didn't get treats, I just started giving a few live mealworms about 3 days ago to my chick that is small (hoping she would start showing signs of growth) and I gave all the other chicks one or two but that's all they've had other than their feed. They have had chick grit for about 2/3 weeks now.
I do think I was keeping them warmer than they needed but I don't think they died due to this.
For the last week, they have been outside and the light is off during the day. I live in GA and the temps are around 70-80 during the day but we did have a few cold nights last week that were about 45 and every night I've been turning the lamp on. Now the lows are going to be around 60 and I'm wondering if I should just be done with the lamp all together?
Also, I started another round of corid last night. I have been doing 2 tsp in a gallon of water, which is the same ratio I used previously for 7 days. Is it possible that with a treatment of corid about 2 weeks ago and medicated feed, they could STILL be affected by cocci?
I really appreciate all the help and encouragement. I've read threads and articles for HOURS and nothing seems spot on. It's funny because I'm completely new to this but when I read other posts, I usually know what the group is going to say yet I'm at a loss with my ladies. I'll post pictures of my set up and see if anyone notices anything that might be helpful.
