We get our chicks in late March. Keep them in the house until they are feathered out and the weather is warm in May. Works out to be good timing for us.
I agree with a soft white light. I use a timer to turn on the light at 5am and off at 730am. I dont use lighting in the evening because I dont want to interfere with their ability to find the roosts.
I have RIRs and Barred Rocks. They get along fine. We live near Chicago and gets pretty cold. I think the Barred Rocks seem to fair better with the cold. Make sure you consider the climate.
I wouldn't worry about attaching it to the pavers. The pavers aren't going to hold anything down. They're not a true footing or foundation anyways. Most sheds aren't attached to a foundation or footing and you don't them blowing down the street very often. The easiest and cheapest was to hold...
If your hens on layer feed they don't need supplemental calcium unless you start seeing problems with the egg shells. Layer feed has calcium added in it.
My girls are alowwwed to free range during the day and are fed layer pellets. I still offer them grit and oystershell. I only have 10 hens so bag of each of those will last me years. If the need it it's there.
We only have 5 hens laying right now. Our other 5 should start laying in a month or two. We sell our eggs for $3.00/dozen. We can't even come close to keeping up. We sell 2dozen/week. Cant really supply anyone on a regular basis so now i feel bad when people ask for them and have to say sorry...
I agree. If they are free range they will find the grit the need. They don't require much and they know when they need it. As long as they are out and about they will find it.
We feed the starter until about 16 weeks but as we close in on the end of the bag of starter we start mixing layer pellets in. I think it is better to make the change by mixing the foods .
