i have a young marans hen (around 15 weeks old) who has become quiet and lethargic today. shes always been a loner and calm but now shes really quiet, sits away from the other chickens and looks 'sleepy' she'll be standing drinking water, then close her eyes and in a sort of slow motion gently sits downwards until shes in a sleeping position on the grond, then even when you pick her up she acts sleepy, doesnt struggle. just sits there in your hands. her comb is very very pale (almost white) and shes drinking lots and lots of water. ive not seen her eat today. her breast bone sticks out terrible, she feels thin and her crop feels quite empty but squishy? also when i feel above her crop (neck area) i can feel 3 hard lumps which im guessing are not normal. one feels squarishish shaped (like a stone) and the other two round. i know a neighbour through over old cherries this week from her tree and im worried my marans has swollowed the cherry stones and they are stuck in her neck??? what do i do??
