Today my 3 lil chicks seem really cranky and sleepy. They were super quiet all night last night, and have been really quiet today. They are sleeping almost everytime I go to check on them, and if they wake up, and I try to interact with them, they really do seem just...welll...CRANKY! They did just lose a chickie sibling yesterday, could they maybe be depressed? They are still eating and drinking and even had their first treat today, which they enjoyed. But, they just are acting cranky and don't want to be away from eachother or come out to play LOL Makes me feel bad but I just want to know if its normal for them to just have an "off day"?? Or should I be worried?
