Hi
Glad you could join the flock! I started my chicken journey with sex link hens and they were super layers and great characters. How nice of you too adopt your neighbours babies from them. Raising chicks is great fun and very rewarding too, I enjoy raising them very much. I have 10 babies at the moment at 4 weeks of age out in the brooding shed and another 27 eggs in my incubator on day 5 so more more on the way! Yay!! I'm sure you will too enjoy raising yours it's great to see them grow and develop there own personalities.
Have you stopped by the learning centre? Lots of articles on raising them and keeping everyone happy and healthy. Here is the link

Wishing you the very best of luck with your flock. Be sure to ask any questions, everyone here to help and very friendly.
Enjoy BYC
