For the BJ57to set up and dry needs to have a warm dry atmosphere for at least two weeks as I recall. Your unseasonably warm temperatures may change before that. You might want to wait for a warmer season.
I used a large brush, I think it’s called a mason paint brush. Something like that. I put down my first yucky layer. About 2 weeks later I used an old kitchen broom for the second coat. That gave me an excuse for buying a new broom. Let me tell you it looks....ugly as sin. But it’s great stuff...
Looks like 38-48 birds can fit in here depending if you go for the minimum PSI of 4SF/bird or give em a bit more room with 5SF/bird. Dontcha just love chicken math?:lau:gig
