Hey ya'll, I'm literally who you would refer to as pawpaw"Farmer Brown". With two grandsons to my credit I certainly love to put they're "hand-to-plow" so to speak from time to time. Now to the point. I've had laying hens before but they were from a neighbor who was tired of them so my wife purchased them and we were off to our first start. Lots of eggs at first but they were getting old and production dropped to nothing and we gave them away. Back in April, I started getting educated and started fresh, building a Brooder cage with all the bells and whistles except one thing. The correct heat source. I had ordered 20 Pearl White Leghorns and lost all but 3. The hatchery informed me the heat source was the problem but they were good to me and sent me another 13 and I still lost an additional 4. Now I have a thriving dozen who are about 9 weeks old. I want them to be the strong and productive as do anyone else would who care about their birds. What is your input about continuing to add the vitamin supplements to their water daily versus every couple days or twice a week? Also I still have them on "Starter Grower"and at what age should I start them on the Layer feed? I have more questions but I'll save them for later. Sincerely, Pawpaw
