Mixing chicks in Brooder

[uncle]

I know this has been covered in the past but I need reassurance.
I have 4- 1&1/2 week old chicks in the brooder and I will be getting 25 more in the AM that are 2 days old.
Should there be any concern in putting the all together?

I think that will depend on how big your brooder is. I have mixed them with as much as 3 weeks age difference. The older ones help teach the younger ones to eat and drink. Just make sure they have enough room that the bigger ones arn't stepping on the little ones. My little ones will climb under the bigger ones wings to sleep.
