Yep. Depends on which incubator you have but a straw and syringe usually works well. You can take the jointed straws and make tubes that will reach a lot of places. I found it best for some of the remote water reservoirs to cut the straws fairly close to the joint, split the end of the straw so one will fit inside the other, then tape them together. Maybe put two or three of the "joints' close together. I had one all prepared but never had to use it. The water I put in my 1588 lasted until the hatch began and once the hatch began, the wet chicks drying off kept the humidity way high. I'm actually going to drill another vent hole in my 1588 so I can maybe drop the humidity once they start to hatch. I had five that did not hatch, I think because of the high humidity during the later stages of the hatch.
