How’d do y’all go about your hummingbird nectar process?

I try to do a gallon at a time so I don’t have to do it everyday

There’s no need to boil the water. Just mix it up in your gallon jug with hot water from the tap. Shake it up and the sugar will dissolve.

I make a big batch, same mix, and fill up empty 2 liter bottles. Use a funnel in the sink. Seal the bottles and rinse them off and stick them in the fridge.

Are you saying you're having trouble transferring the solution to the feeders? I've always done the same as you, mixed up the solution and put it in a gallon jug to cool and store. I pretty much use the same procedure to pour it in the feeder. I will add that I have a lot of pouring experience due to my beer drinking habit.

We are making 1.25 gallons every 3-4 days now which will crank up to about that amount per day by the first week of September. The 1.25 number came about because that volume of water just touches the handle rivets on the stockpot we use to boil the water. We don't even measure the water any more (but we do the sugar). As mentioned earlier, you don't really need to boil but old habits die hard!

Once cooled down it is poured into a couple of old orange juice bottles with a funnel - easier to store in the refrigerator. And easy to get into the feeder bottles.
