This afternoon's project: bleach out and prepare another rubbermaid and transfer 10 of the peepers to their new home (it's a slightly smaller bin). I'm running out now to pick up more pellets, another feeder and waterer, and when I get home, I will rehome the girls. My son will be out there with them in the meantime to supervise their antics! Thanks for the advice...I feel badly that the little one got smooshed, if it was my fault for having too many int he brooder. The coop will be ready by Monday, and since the weather is warming during the day and since we can hang a heat lamp in there at night or if temps drop, I'll move them outside earlier than planned. Thanks for the help!
ETA: Question: once they're separated into two brooders, it seems sensible to mix them up--as in, don't leave the same chicks with one another as if they are 2 separate flocks, but give them all a chance in both bins, and mix up the combination of chicks, so they don't form a "chick clique" and have to be reintroduced. If the coop is done this weekend, this won't likely be an issue, I guess,but just wondering...probably overthinking...
