Respiratory infection Help!

Hi I have had ball python for about a year now have them in a rack system have 15 as of now and then two of my snake a girl cinny and girl pastel have it what should I do? The thing I don't get is that they did not get sick during winter and now it got a bit warmer and now they got RI. And does any one know a good vet around Bakersfield CA hope you guys can help thanks.And does any one know about how much treatment cost?

Are those tubs near the bottom? Sometimes temps can differ from top to bottom. What's are you heating with? Check all of your connections. They can easily get an RI if let's say those two girls were wintering themselves and have been staying on the coolside and your night time temps dropping and making it too cold for them at night and then they aren't getting warm enough during the day. But how they got the RI is not the issue at hand. I can't recommend a vet bc I'm way across the country. But a usual vet visit to my herp vet is at least 100-200$. They'll need antibiotics so that will cost, but its really the only way.

Well the rack is 7 levels and each level has it's own piece of heat tape it is not one big piece and I saw that some levels Are diff temp than others

Ok the levels that they were on what were the temps? Ill bet money that they were too low. The problem with having so many connections is just that there's more of a chance to have a connection go haywire and stop working. If I were you I'd go through every connection. And check the temps. Also I would completely change those multiple peices to 1 piece that gets weaved in and out if the rack. That way you only have 1 connection to go wrong and you'll know it bc the whole rack won't have heat.
