How do i tell how old my chicks are??

[AshleyB87]

I few weeks ago I bought 6 baby chicks from Tractor supply...How do I figure out how old they are and how old I have to keep them under a heat lamp?

When you bought them at tractor supply there were only a few days old. I think i had mine until around 7 weeks and let them out in warm weather.(or until they develop all their feathers)

Well when the store gives them to you they are usually 3 - 5 days old. They will need to go outside once they are about 8 - 10 weeks.
Good Luck!
