Just curious...........and certainly not attempting to tell you what to do, in any way.......but I 'am' wondering why you are having
such ammonia smells? And 'wet bedding' you're trying to dry out with your fan?
On your website, it says you just got you chicks on June 11th.
May I ask, how big your coop is for 25 chicks & 5 ducklings?
What are you using for bedding?
They are too young to be roosting yet, but you may want to consider a droppings board under your roosts, for when they 'do' roost.............as 50% of their poo will be deposited at night, when they are roosting. I clean the poo out of the shavings (on the droppings board) each morning.......with a kitty litter scooper; and any poo that 'is' in the deep litter on the floor, I just turn
over and 'fluff' with a pitch fork. I also have DE mixed into all the pine shavings...........on the floor of the coop, on the droppings board, and in the nest boxes.................and I can honestly say there is absolutely NO SMELL what-so-ever in my coop! For real!
I believe the DE does so much to dry up the poo and control the odors, I cannot imaging managing chickens without it!
I don't believe you should be smelling ANY ammonia in your coop, if things are being managed well.............and you shouldn't
need a fan to 'dry out' the bedding. Any wet bedding should be 'discarded' and replaced with fresh bedding. I fear your birds are
in danger of major respiratory issues. If you can smell ammonia where 'your' nose is, it is quite a bit worse down where your chickies are!
Any questions on coop management, please ask away. There are so many wonderful people on this forum who can help.
