mixedUPturk- Thanks for the welcome! That's exactly what brought me here, unfortunately, but I got to looking around the site and I love the community and how friendly/knowledgeable everyone is!
I'm in SoFla, so you're right, the weather is very similar. I don't, however, have a safe place to keep them outside. I used to raise ducks in my yard and we had a huge problem with raccoons, fox, and cats getting into the enclosures and having themselves a nice dinner. Right now I'm living with my parents for a few months while I find a new house that's closer to them, and they keep their garage air conditioned, so it's not a good place for the chicks, either. I do, however, have my adult buttons out there, and they're quite comfortable. (with the AC, the temp still only gets to about 78F, 76 at the coldest, it's only a wall unit.) They don't have a screened in patio, either. (this is where I used to raise the ducks in my teens/early twenties.)
The good news is that I've kept the temp in the brooder at about 85F and it's naturally humid here, so I haven't had to adjust any of that. All the chicks seem comfortable, and it seems that it doesn't matter if I increase or decrease the temp, they just like to huddle when they sleep. I've moved them away from any AC vents and over near the window, so they get natural light and some heat from the sun. If they're cold, they can move into the sun, or if they're too warm, they can move out of it. Part of the brooder has shade. They love the sunlight. Lil Buddy's toes are doing better. I did a few Epsom salt soaks, and the swelling has gone. The black parts of his toes have fallen off, save for the one that was completely black. I don't want to touch it, but I think it'll fall off any day. I haven't noticed any more swelling or blackness, so I don't think it's spreading. I'm pretty happy with how they're doing!
Just wanted to say THANK YOU to everyone for giving me advice on what to do/improve upon! I really appreciate it! Lil Buddy says thank you, as well!!
