Wavechickens
Chirping
Update:
So I have 19 laying chicks now (original 13 and then another 6 I got this past week) also 4 that we are raising for meat
The 2 ducks multiplied into 4 after a visit to Tractor Supply and we are getting 2 geese and 2 turkeys that will arrive the week after easter.
The oldest (4 weeks) are living in the spare bathroom and are getting too big for the brooder but the coop isn't ready yet and its too cold outside for them at night not sure what I am going to do with them until we can get some heat out there. We had placed the younger chicks with the older ones but there were problems so I had to separate them into their own brooder. Now we have 3 brooders (Older chicks, younger chicks and meat birds, and Ducks)
My family believes that I am crazy but they are enablers so we are happy.
The little babies 4 weeks ago have changed so much I heard someone refer to this stage as the ugly stage tho I still think they are still pretty in their own way tho scruffy looking and their little cheeps have changed not quite clucks yet but getting there.
I will share pics of them tomorrow and maybe the coop
I totally understand

As for adding the groups together you may run into an issue there, chickens are very temperamental sometimes (depends on the breeds and individual chickens). There are a lot of suggestions on how to introduce them to each other. We ended up getting them all at the same time as day olds to avoid it. In the past (many years ago) my parents had chickens and attempted to add new ones after six months of bring separated but togther they finally could kinda coexist.
Best of luck, i would love to see some pics of them!
