HELP sick chick not eating/drinking, lethargic, congested - what do I pick up at the feed store?

[Whispering_Raven]

.....I started taking my chicks outside from day one. I could be completely wrong, but that's what mother hens do, and I think all growing things need some sunshine to be healthy. ....

I totally agree! I haven't been able to read the updates until now. How are the babies doing?
