Mom is doing great. I think with having 7 other chicks to tend to she has no time to worry about Runt. He slept well last night and doesn't appear to be sneezing very much today. Appetite is very good and I checked his poop and it all looks good to me. He has been roosting most of the day. My husband took him outside for a stroll in the yard and he was pleased as punch to be outside.
