Hello, Luis, and welcome to BYC. What a nice flock you have there! I am sorry for the one you lost, but congrats on all the rest being pullets! You probably should buy a lottery ticket because you are one lucky guy! I look forward to hearing more from you as those birds get into all sorts of interesting adventures.
Welcome to the coop! I use the Forums and Articles tabs at the top of the page to do research. You can get lost for hours. It's nice to know you are minutes away from getting help with questions and emergencies! I always check in the "What's New" section as well at the top of this page. This way I can read how I may have a similar question or help give some advice.
