My husband and I have 12 chicks, approx. 4 wks old, 3 of each: barred rock, road isle red, black sexlinks and ameraucana. Today, we woke up and noticed blood atop their bedding. It doesn't look like bloody stools so much as it looks as if a chick or a group of chicks got their periods. The blood is soaked into the bedding, and it looks runny, as opposed to clumps in stools or traces of blood in stool. They all still seem energetic and are eating and drinking fine. No alarming noises or out-of-character behavior to indicate they may be ill. We are very worried and care about our chicks a ton. Any advice will help. I'm thinking about taking a sample of the blood to a vet this morning, but I will be late to work. Mahalo for your quick replies! *** Other facts about our chicks: We got them from a local resident who raises, sells, when they were one day old. They are feathering out, all normal size, with normal energy levels and behavior. We are keeping them indoors for a couple more weeks and have kept a heating lamp on until a few days ago. Area is well-ventilated and not too warm, not too cold. We've fed them starter feed, with hard-boiled eggs sometimes. We've taken them outside a few times and they've eaten a few worms, digging through the grass. No pesticides in area. Grass and land is good. No vaccines or antibiotics have been used on them as of yet.
