I might have it closed more than during summer as it has been -8 degree Celsius and i am trying to keep heat in, tho still fresh air can come and go.
The area where the little ones house I built this spring, had chicks in there ever since and never had any deaths until now.
But the 2 adults that died were never in that area, only in the adult section, seemed to have breathing issues as well, tho that coop is open during the day as i free range them.
The Amprolium acts as a Thiamine blocker and helps to starve out Coccidia so the chicks can build resistance. Hard to know if they are too far gone, but it's worth treating to see if they can fight it. It's possible they may have intestinal damage which might affect them later on.That should slowly cure tho now with Amprolium unless they are too far gone already?
I was wondering now that i am giving my whole flock Amprolium in water source, will it react negatively to my adult chickens? I did feed those medicated feed for like 4 months when i first got them 3 years ago
Amprolium will not hurt the adults - it's mild and there's no egg withdrawal period (in the US). The amount of Amprolium in medicated feed is "tiny" so even if they were still on medicated feed, it would not be a worry.
