What Size Elbows for a Chick-Sized No Waste Feeder?

[3KillerBs]

I'm a deli clerk so I picked up a couple 5lb containers from the tuna and chicken salad to make a no-waste feeder and a mini-nipple waterer.

What size PVC elbows do I need for chicks?

1.5-1.75”

my 3 sizes -14-21 days, 3 weeks to 10 weeks , 10 weeks to death

Thank you.

DH has a box of assorted plumbing pieces so I can probably find suitable elbows now that I know what size.

I have essentially unlimited quanities of 5lb deli salad tubs if I goof up the first one.
