So far Sky seems to be feeling a little better each day. He's still sneezing though. He has a hearty appetite but he's also starting to get some diarrhea from the antibiotics. I bought some plain yogurt today and gave him some this evening. Luckily he seems to love it. I'll give him some more before I go to bed. So far all of his brothers are fine too. Hopefully he'll be back to his old self in a few more days. Thanks again everyone for all of your concerns.
