Hi, I got my chickens on May 9th. They were probably hatched on May 7th--so about 31/2 weeks today. All but one seem to be progressing normally with good feather growth. One of the Plymouth Barred Rocks seems to be very slow on feather growth. She sits on her hocks and doesn't roam as enthusiastically as the other chicks. When I went out to check on them a few minutes ago, the one that isn't doing so well--Janie--was acting like she had hiccups. Because the weather is warm now, I started letting them out into their covered yard during the day. They have really gotten active grazing in addition to eating their normal chick starter. I put them up at night and they are still sleeping under a brooder lamp. Any suggestions on what I should do? For example, should I isolate her? Should I put her back in the coop and keep her there instead of letting her out during the day? Thanks!
