It's still alive today. I got them a bigger box so they have lots of room for now. I will just let nature take its course . It doesn't seem any worse but still weak/sleepy
I've found the ones that aren't going to make it do a lot of peeping with their eyes closed. Hopefully your little one will perk up. I had one I was worried about recently but it did improve and it's about a month old now. Sometimes they take a few days to recover, then they are right as rain.
