Good morning, I have 6 chickens that I hatched using an incubator about 4 weeks ago. They are all getting nice feathers, beautiful colors. I went to a local feed supply shop here in Canada- more specifically in Brampton for those who might be from around here. The person at the store said that I can start feeding them an egg layer feed after they grow their feathers. Couple questions I have which I'm not clear on: 1. I know I have at least 1 rooster. If he gets at the feed will it have any unwanted affects in him? 2. Do I have to isolate the hens and make sure only they are getting the feed? 3. If the rooster is not present, will the hens continue to lay eggs? 4. What age will they start laying eggs? The lady said I should start the feed now, and they should start laying within 3-4 weeks of starting the feed. Any other comments or suggestions would be greatly appreciated. Thank you.
