I use Dumor brand. I feed chick starter till they get their feathers then I mix the starter with scratch grains. When they're about 4 months old Ijust feed the scratch grains and give them vegetables and fruits and what ever I have from table scraps that isn't greasy or spicy. I make a mixture about once a month that has cooked rice, tuna, crushed egg shells, apple sauce, crushed oyster shell and a green canned or frozen vegetable oatmeal. I don't feed carrots because I was told it will change the color in white birds. I don't give any citric fruits and I drain the liquid off of the tuna, rice and canned veggies. I've used applesauce alot because they seem to really like it. I make a gallon bucket full of the mixture and I drop in in their run by spoonfuls. Idon't put more than what they will eat in a day to avoid drawing flies.
When we do yard work and find worms we toss them in. They love them. Go to the bait shop and get cricket and toss them in. It's great entertainment. I give mine left over cornbread. The juveniles get to free rance usually a couple hours a day because they have no run on their pen. They have a concrete floor covered in wood shavings. I don't leave them out long to avoid a hawk stealing any or the bobcat that lurks around here.
I give electrolytes when it's the very hot summer months and only vitamins when I have a chick thats not as strong as it should be. When the pullets start to lay I add layer crumbles to scratch grains. I use mostly metal pans for the food and I put a 1 gallon bucket of layer crumbles to a quart of scratch grains. I'll toss a couple of handfuls of scratch grains in the run when it's dry weather to give them something to peck at and scratch around for. I put grass shavings in their runs when we cut the grass. I also keep oyster shell in a separate dish for the broody's and in the main food dish.
I also check their feet for injuries and dirt that has collected on their nails and feathers. On the breeders I trim the feathers on their fanny and lower around the vent. I've never trimmed the feathers around their eyes but I do have one that I need to do that to. She will get up on the nesting shelf but won't get back down. Probably because she can't see well enough to get back down.
As far as nesting, they kind of pick what they want to use. I put different things such as a box or a plastic tub that doesn't have tall sides, bins and baskets. I have nesting shelves too. I put wood shavings in them and they pick what they want. I remove what they don't want. Some just prefer the ground. they will kick out what shavings they don't want. In one pen they use the shelf, another pen they use the ground, another pen they use a plastic tub and my bantys prefer the bin. My house chicken prefers a basket.
My first silkies I got last year started laying at 6 and 7 months old. They started laying in the fall and went broody soon after and stayed that way all winter. I have 2 hens now that are broody for their first time and they are a year old. My house chicken went broody when spring hit and I gave her some eggs and she now has babies. I've given her a couple more chicks and she takes care of them as if she hatched them. She would never defend herself but she sure defends those chicks even against me. And i'm her cuddle buddy.
For me, sexing a silkie is very hard to do. My first ones I had to wait to see who laid an egg before I knew which where girls. Now I go by their crest feathers, if that still has me stumped I wait till they lay eggs. If they crow I know it's a boy.
This site is very helpful and you should learn alot. I am no pro when it comes to silkies but there are things I do know because I learned them form this site. I'm still trying to learn.
