Suburbia

[tectak]

Flamingoes stalk the grass in rows
and gnomes mould mushroom huts;
old men keep them waxed and posed,
for children run amuck.
 
The bake sale draws a modest crowd,
but teens bring uncooked eggs,
their shells lie broken, disavowed,
while mothers cry, “For shame!”

A delight. Runs like clockwork, no surprises, pleasure to read and visualise. More like this, please.
S2, L1 and L2 make a complete sentence. You may consider starting L3 with a generic descriptor to start a new sentence and avoid the "their" ambiguity. What is the old fool rabbiting about?
The bake sale draws a modest crowd
but teens bring uncooked eggs.
Brown ( pale, white, thin, sharp) shells lay broken, disavowed
while mothers cry, "For shame!"

That is all.
Best and good egg,
