Hi all - I'm a newbie to all things chicks and chickens, so please be gentle with me, I'm doing my best and have no frame of reference to base anything on. Got 6 chicks on Friday. One came from a local farm, the others from a place that orders from a hatchery. The single chick seemed lethargic when I got her home and in the brooder. When I got the rest in the brooder that afternoon, the singleton from that morning perked right up. Seemed to be totally fine all day y'day as well. Today I had them outside in the sun for an hour or so and they all did well. Tonight the one singleton chick seems to be lethargic again, though only slightly. She is slow, not hopping around like the rest, seems to stand there motionless for short lengths of time. No mouth breathing, no droopy wings. She also drinks a little and eats a little on her own. We are using the heating pad method in the brooder which seems to be working well. I'm also cleaning everything out daily. When I got the 5 hatchery chicks, the woman told me I don't want to use medicated chick starter, which I'd already purchased (Manna Pro). So I bought her natural chick starter that is unmedicated. She also gave me one packet of electrolyte powder (Sav-a-Chick) and said to mix it into a gallon of water and use that for them, and that I'd only need to give it to them until the one gallon of it ran out. I asked if I should put anything else in the water and she said no, but I'd already bought Nutri-Dench earlier in the day. I didn't add it to the water, I just gave them the electrolyte and her company brand chick starter. Now I'm reading that some people use nutri-Dench on lethargic chicks, and that they will also use medicated chick starter as well. I just changed out my food to the medicated one and added 2oz of the Nutri-Dench to the gallon jug I had the electrolytes in (it was still half full) and filled the rest with water - and I refilled their water with that mixture instead of the straight electrolytes. Is there anything else I can do for this baby? It's like she isn't growing, because I've noticed a change in the others already, but while her wing feathers have grown, the size of her has not. There's another tiny one in there as well who was slightly lethargic, but she seems to be doing better and is definitely better than this one little one. And why are they so small? (one is a Cream Legbar, the other small one is a Blue Ameraucana). Here's a pic of them from Friday, and another from today. I'll add a link to a video of them eating from my Instagram account so you can see them in action and see just how tiny this one is. The one I'm referencing is the Cream Legbar chick, which is brown with stripes on its back. If anyone has any advice for me, I'd be very appreciative! This is a pic from Friday. The chick in question is the teeny tiny one on the bottom right, who was 5 days old in this pic. The other questionable chick is the one just above her to the right, hatched on 3/22. I was told ALL (other than the tiny one) were hatched on 3/22 but when I questioned it and asked why a few were larger than the others, she gave me the "well they're close to that date but are probably a little older" kind of casual answer (she doesn't hatch them herself but I'd like to think that was something she'd know the answer to). Here's a pic from just now. Can you see how the others are growing but she hasn't? You can also see her wing feathers have grown well, but it's like her little body stays the same size: And here's a video from yesterday if you care to click on it and take a look, from my Instagram account: Baby chicks eating, size comparison Help?
