Sneezing / What age to give new chicks supplements?

[Rebeccakelly1000]

I have 1 chick who is 7 weeks old and 3 more who are 8 weeks old.

Late last month i used Verm-X to help prevent worms and today i have supplemented their drinking water with Apple Cider Vinegar and used a mite blaster on their bed. The last few days they have moved to an outhouse while i get their coop ready.

I would like to know when it is suggested for me to use:
Poultry Tonic, Mineral boost, Poultry spice, seaweed or garlic?

Also they seem very alert, eating and drinking well and look healthy, however i noticed one sneezing yesterday and now another chick is sneezing too. I have read that this may be due to the change of environment and should settle soon. Has anyone had this with their chickens/chicks? They are off heat and are eating growers pellets. They are free range and eat a lot of spider webs!

What bedding are you using? If this is at all dusty, or if you are using hay, this may be irritating their bronchial tubes and causing the sneezing.
Personally I wouldn't use any supplements on chicks at this age. So long as they have access to fresh clean water, nice green food, and are just transitioning from chick crumb to growers feed, all their nutritional needs will be being met.

Thank you Marigold for your reply.
I am either using straw or wood chippings (borrowing them from the stable) at the moment. I didn't really transition them from chick crumb to growers feed, just switched to growers when the crumb was very low and stuck with growers ever since. They are eating it fine. They are not confined to their box any more but can run around in the room they are in. I set up a roosting bar using a broken mop pole on 2 upside down dog baskets which they do sit on.

Green food: is that grass or green vegetables?

Grass to nibble if they can have a little covered run outside during the day if its warm enough ( don't let them get wet) the new Autumn shoots of grass are very tender and attractive for them. Otherwise, cabbage is good. They like lettuce but it has no nutritional value. Mine also get apples or other fruit peelings, tomatoes, and love a cob of sweet corn now and then. Not too much, it's just to make life a bit more interesting without totally filling them up!
They don't need to have a perch until POL. If they are a light breed it will probably do them no harm, but people who raise heavier breeds such as Orpingtons sometimes claim that perching too early may possibly damage the correct formation of the breastbone. I don't know if this is so, but I bet they look sweet on their little perch! Would love a photo. They will soon need something wider than a broom handle, though - minimum 2 inches, with right-angled edges planed off so not sharp. A cylindrical narrow handle won't be very comfortable.
Don't know about the sneezing - are you sure they're all warm enough, especially at night? Don't risk them getting chilled as they adapt to outdoor temperatures. At 8 weeks they are fairly well feathered up but this process isn't complete yet.

They are free ranging now, so can eat as much grass as they like, they like to scratch around in the earth a lot though and love spiders webs and flys! Its very funny watching them run around trying to catch them!

If anyone wants to have a crack at trying to sex them, i think i have 1 yellow cock and 2 yellow hens and the millefleur might be a cock.

p.s the house will be cleaned out i.e poop removed.
