sell him ,eat him ,put him on craigslist or just save him to build your flow but be sure to have another pin to put all roo in to this you wont have to many roo per hen
that is a very nice coop ,but for me I have to say that chain link fence would have to go, I guess that is because I am more in to free range chicken, I feel that the more room a chicken has to range around the happier they are ,but again that is just me.
job well done it really does look good
rookie have to stick together I would most likely of tried to clean them up,but I think I would have used a damp rag and lightly wipe them off not know if that is the right think to do
get them all in the coop for 3 day in a row and at each night when you all of them in the coop close it off and maybe they go in the coop every time after that
not sure if this will help but you can hold her in your hand and close to your heat lamp 10" away until she starts to come around ,like I said I do not know if it will help, that is what I did when the rain came and I had put the chicks out side in the morning and then we all took a nap around...
it could be the heat just keep a lot of water ready for them mine are going though 2 1/2 gal. a day
p.s.
don't forget to have good open shade with a good air flow
because of the heat I put a water jar in with my brooder she has hatch 4 chicks and I am guess she still has a egg or 2 to hatch. that is because when I saw her there was another hen in the same box laying eggs too and I put one or 2 under as well
