am new to the chicken world. Have silkie babies that r 1wk and 2 wks old. The blk one r getting sick. eyes closed, sneezing a little,not wanting to eat r drink. I think the first one that got sick is going to make it.He is getting stronger he is 2wks old. This morn I found another one sick. They were all good last night.I do not think this one is going to live .them is good ,no draft. Not sure what is going on. Any and all help would be appreciated.
