Lost a chicken Jan 9th, the rest of the flock seemed fine. She was 4 years old so I wasn't sure why. Lost another one Sunday morning, so I got on BYC and read and read and read...figured it was Coccidious. So I went to Tractor Supply and bought COCCI, have been treating since Sunday. 1.5 tsp per gallon 20% solulable solution. I also mixed it into the water that I use to make their mash, I only make mash to feed them, no pellets. I fed a mix of mash, oatmeal and other cereals the kids have left the ends of, plus breads, veggies, fruits are thown on top. At night they get scratch to fill tummy's before the long night. The one that died on Sunday I noticed on Saturday she was alone in corner, wouldn't come to me for scratch and treats and just seemed very sad, she let me pick her up and I held her for awhile. The next morning she was dead in the same spot, she never roosted. Temps have been cold, but only 3 times have I turned on 1 heat lamp as it was -15 one night, -22 two other evenings. The light gets turned off at breakfast. I noticed strong ammonia on Tuesday and we put fresh pine shavings down, they had spilled the water. I open the pop door almost every day but there is 4+ feet of snow in our yard and they won't come out even if the main door is open wide....they just basically seems to scream at me looking out -- I find it funny. My coops is 8 x 10, I have 21 hens....3 Leg Horn, 3 Golden Wyandotte, 1 Unknown (small hen) 1 Barred Rock, (now) 8 Red Sex Link, 5 Road Island Reds. Please let me know what I am doing wrong.
