That's awesome you were able to find a kiddie pool this time of year, they look like they are loving all the extra room

You may end up needing to put chicken wire around the pool as they get bigger so they don't jump out.
They grow up so fast, hang in there. Our babies are 5 weeks, so messy and also cleaning 3x a day. They get so excited when their brooder is clean that they poop and then head right over to mess up their water, lol. I can't wait to get them outside but also miss having them inside when they are all grown up.
