i just found my chicken frothing at the mouth in our coop. earlier we had sprayed great stuff foam spray onto the cracks in our coop and she ingested it. there was a big lump in her throat i figured was the hardened foam so i brought her in and pulled out the blockage that was in her throat, a mixture of the foam stuff and her food. the lump is gone now but i don't know if she ingested any or what!! Please help me ASAP! nor do i know how toxic it is. any help appreciated
