Some hens are the shape of a heart-- specifically a Serama hen. Perhaps you could make your heart BE the hen and then use the coop roof. With the heart, the hen and the coop roof, it is a bit busy.
Also, picking up the city is great; converting your city into a suburban neighborhood (I haven't any idea how), would be even better.
#79 love how you conveyed the heart in the hen body and the eggs on the ground, not on the hen. The eggs IN the hen are also cute.
Actually, I think I like your original heart with the hen inside better #65, but with #79 homes.
The tail on a hen sticks up or out, but doesn't have long feathers that bend down.
Could you try using the coop roof and window idea from #67 as the background (instead of the houses) with the hen and heart from #65 and eggs from #79?
