Now I have another one that's starting to slow down on the food and water, but now I'm giving them antibiotics through the waterer and it seems to be making her and another one very sleepy which prevents them from eating as much as they use to. I'm using vetrx and probiotics.
Also 2 of my olives lacked eating after I switched to Purina organic starter feed since the crumbs where a little bigger than the other brand I had. I've also been giving them hard boiled egg yolk, plain yogurt and I'm crushing the feed to encourage them to eat.
The temp is 91° Fahrenheit Under the lamp and 86° Fahrenheit outside of the lamp,
I've been treating all of them for a respiratory infection because I'm worried they are passing it on to each other.
he 3 left have semi solid olive stool, but every other day I will find a couple stools with a little red in it.
I'm sorry for your loss.
First of all, I agree with @azygous I would start treating for Coccidiosis, asap. You can find Corid in the Cattle Section of Tractor Supply. (see photos below).
Dosage is 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.
If you can post some photos of the poop that would be good.
I pulled some info from your posts, I may have not read all of it thoroughly, but a few things stand out.
Your temperature - you keep adjusting it? Are you trying to keep the whole brooder at 91F? At around 9days old (?), chicks should be at around 80-85F, but they only need one warm spot in the brooder, let the rest be cool - I don't necessarily go by temperatures, I look at behavior - if they are all huddled under the heat source cheeping loudly, then they need a bit more heat. If they are spread out avoiding the heat, it's too hot. Panting - they are too hot. (Panting can also be a symptom of Coccidiosis). I brood chicks for the most part outdoors under a heating pad, that provides the one spot of warmth, my night temps get into the mid 20F and have had no problems - sometimes the days are only in the upper 30s/40s, chicks will run under the heat when they get cold, so watch behavior.
You mention that you got antibiotics from the feed store - what did you get and what dosage are you using?
I'm concerned about the antibiotics making them sleepy?
You are treating for respiratory infection? Are they coughing, sneezing, have runny noses, facial swelling, pus or discharge from the eyes?
You also mention they have trouble eating the new crumbles because they are too big? You can wet the chick starter to make a mash which is easier to eat for small chicks. Just put some in a bowl, add warm water and stir. My flock loves wet feed, they eat it from day one on (dry feed is also available). Hard boiled egg is a great treat, so I would give them a little each day, no problems there.
Also, do you have the packaging your heat lamps came in - what type of bulb are you using - especially for the EE's?
