I realized that I never mentioned that we got chicks last weekend, so I let the kids have the camera to document them for you:
So there are now 6 chicks living in our garage again. Three of them are Isa Brown pullets. The other three are possibly (probably) Rhode Island Reds. The guy working at Tractor Supply that got the chicks for us was not a knowledgeable chicken guy, and so the Rhode Island Red label is really just a guess. We also aren't sure if those three are pullets or are straight-run.
So these 6 chicks will eventually join the 6 hens and 1 rooster we have in the coop. For now, though, they are enjoying life in the garage.
