i have 1"x 1" steel mesh in my avairy sloid to walk on, have also just used it on a kit box for my rollers it comes in 8x4ft sheets, a pic of the floor as i built it, i then fit trays underneath that i just pull out and clean.
this was asked last year and at the time i had a round of eggs due to hatch i noted every thing i spent on corn ect for the next 28 days, after deducting for corn that i would have fed obs anyway, it was just under £5 per ybs.
i think its a wind up in the vidio thay dont name the player,and depending what link you read thay show a differant name at the bottom same fee 83 million.
the shed cost me £50 the aviary was built out of bits i had left over from building an aviary for my canaries, got a shock when i went to buy a roll of felt for aviary roof it cost £21, so my full cost now stands at £71 for total build,
it may look dark inside from the photo but its not, it has a full mesh floor,the aviary is yet to go on the right hand side,the birds will be put in when its all done.
hi mate just to say thanks for the rollers you gave us and brought them over to blackpool,I will be breeding a round of ybs for mark from them, atb kirky & oldyellow.
