It's winter time so we are starting to dry laundry indoors. However, I noticed a huge amount of condensed water on our windows because of this which means the air is very humid. Could this be a problem for budgies? One time when my budgies were babies and one of them was sick, a vet told me to it's a good idea to keep them in a warm and humid environment, like bathroom. I obviously don't keep them there but I was just wondering could it be too humid and could they have problems because of detergent and fabric softener? For now, I try to keep the laundry in the guest room but it's so small it gets humid really fast and we're having guests soon so I'll have to move it somewhere else.
You don't need to worry that the humidity is too high because of the condensation on the windows.
Many people buy and run humidifiers in the room where their birds are housed (including myself) to ensure the air is not too dry so I often have condensation on the inside of my windows.
