[Spoilers] Post-SFS anvil chicken automation

[Kazuya Mishima]

As i'm getting a bit tired eating melon slices and boiled potatoes i've been trying to automate food production. Animageddon made all automated animal production seemingly impossible. I designed a 4 piston grass cycler that pushes grass under a feeding chamber as the turntable turns.

The idea seemed relatively foolproof:

As long as all the grass upon the blocks was not consumed during night. As I launched an egg into an opening in the feeding chamber and hatched a chick it settled upon the grass and after a few turns of the system the chick phased through the block that had been pushed under it and suffocated.

I'm guessing this entire design needs to be scrapped?
Would an adult chicken just not block phase downward? I'm wondering if my problem is i'm using a baby chick and they are more likely or ONLY ones like to phase.
I would also like a way to do Nether contaminated feather automation. This is the only viable system I could think of to offer an automation path. Anybody able to automate chickens and prevent block phasing?

You need to use slabs for the conveyor, not full blocks. Also you can get much higher grass density for spreading to make a smaller footprint. https://imgur.com/a/e8PFbn2

Thanks. It just never occurred to me to use them. Also that grass thing blew my mind.
