Ok I have 19 buttons 1 chicken and 4 cortunix chicks in my brooder , no squabbling that I have seen. Today when I got home and was giveing them fresh top off on thre bedding , fresh water and fresh food I noticed a few very small dried up smears of blood on there feeder. It wasnt there when I gave them there morning fill up. I checked all the cortunix and didnt see much of anything except a little poo on there toes , I checked a few buttons by picking them up but there so spastic I try not to freak em out to bad , so I sat there and watched them for awhile and no one that I could see was limping , had blood on them or seemed at all distressed. I will most likely wait till my son and cat are sleeping and look over everyone again ... Any one have any ideas . I use one of hte metal round chick feeders with little round holes in it for them to eat out of .
