Welcome! Just wanted to pop by and say, I was angry when I came home to 4 little fluff balls in a brooder our basement, too. They showed up without my consent or even so much as a hint ever that they were going to be there. I kept calling them his chickens and I wanted nothing to do with them. Let me tell you, they stole every piece of my heart very quickly. I hope you will grow very fond of these chickens. If anything I hope they provide you with some entertainment and healthy, delicious breakfast. Good luck on this journey!
It's never any fun being thrust into anything. Been there, done that, although not with chickens. I'm so sorry. Nevertheless, I truly hope this turns into something positive for you!
Big welcome to the forums! Let us know how else we can help. And bless you for giving these animals a home when they needed one.
