I recently purchased 8 Rhode Island Red Hens and 1 rooster, all about 20 weeks old. I modified a section of my barn to accomidate them. Are there any major things that I should avoid doing or things I need to make sure I do to keep them healthy, happy, and laying eggs? They have not laid any eggs yet. I am providing them w/ 14 hours/day of light, but no eggs. Can I expect eggs anytime soon?
