In the Brooder
My brooder is a Tupperware box with an infrared heat lamp. I have a thermometer and then box has stayed between 100 and 95, but is big enough for the chicks to move out of the heat if they get too hot. I have pine shavings, a chick watered, and medicated chick starter crumbs. I change the bedding probably more than I need to because I'm trying to keep it super clean for them so they don't get sick.
This morning I noticed the two smaller chicks weren't eating and drinking with the bigger 3...again I was starting to worry....noticing again that they just weren't growing like the others. All of the poops seem fine....but they are seeming a little lethargic I thought...one was making a sort of muffled peeping sound and I wasn't sure what that was about and after a second it seemed to clear up.
I left for the better portion of the day today and returns to one of the smaller Cream Legbars I've been so worried about dead. Now I'm terrified that the other is soon to follow. I've switched the water in the brooder to sugar water but she still isn't eating a lot. She kind of stumbles and I don't know if it's her being little, or weak, or sick. She's not as assertive as the others and will offen stay out of the hustle and bustle/chaos the other three create.
I've attached a photo.
What do I do? Please help
