Rat help!

[pinkeye714]

I have a whole rat breeding setup for my snakes (it works well but a pain with glass tanks). It is set up in tanks. I wanna make a rat rack (8 tubs high) using petmate cat litter pans. What do you think of that or should I use concreat tubs from lowes? I keep my rats in my horse barn. The barn is un-heated, and i live in upstate NY. I have bought rat for the longest time but i started breeding this spring. What should I do for winter? I have a garage but its probly just as cold. should i move them into my house? P.S. my bp's wont eat F/T. Please help.

do you have an electricity going to the barn? Depending on how big the area is, you can maybe just go to CVS or Walmart and grab a portable heater. the heaters are no more then $30, i got mine for $20 when living in cali and it warmed up a master bed room quit well. they are small but can do the job.
