I cant seem to breed them outside the nesting pins they wont take seeds.
in addition chickens dont seem to drop specialty drops in nesting pins SpongePowered/SpongeForge#1259

Wrong mod Hatchery and Chickens are two separate mods by different devs. But the Chickens mod dev has been MIA for a little while now.

And really you should report this to spongeforge

it was reported and its only when the chickens are in the NESTING pins they dont drop the item like flint chickens dont drop flint iron chickens dont drop iron ETC. they do when they are in the world

Ok but if you read your first comment you said.

"I cant seem to breed them outside the nesting pins they wont take seeds." << Chickens..

I already know about the SpongeForge issue. Its a sponge forge issue.

Im guessing the wont take seeds is a spongeforge issue too.
