i had 60 chickens that i purchased as day old chicks and everything has been fine up until this point. i got 30 white leghorns and 30 rhode island reds. for some odd reason that i cant figure out is that i now have 53? chickens and i only have this many because my reds just die with no signs of sickness that i can notice. there has been 5 that have died in the last 2 weeks and i dont have a clue why.but its just my reds and when i ordered them they were vaccinated for mereks disease. i have only had 2 leghorns die when they were peeps because they were the runts and they got killed by the others. and now the leghorns are laying their pullet eggs. when the first red died she showed signs of sickeness because she just laid there and wouldnt get up and the next day she was dead but these others just die with no visable signs. if someone could help me i would greatly appreciate it.
