Sick 5 day old chick

[BTreadway93]

I have a sick chick and I’m not sure what to do. It isn’t eating/drinking much, huddles near the heat, and doesn’t move around much. It had pasty butt 1-2 days and I cleaned that off. It’s 5 days old now. It started going downhill yesterday. I’m thinking possible coccidia or mushy chick, but I’m not sure. I’ve never had one sick before and this is my 3rd batch. Another one died yesterday. It was fine and the started acting lethargic yesterday morning and was dead after lunch. I appreciate any help!

I'm sorry. I don't know how to help. I have one sick now too. I kept 26 chickens alive for years and now these 21 are absolutely killing me. I ts like I get one better and then another one goes downhill.
