Chickens without a coop

Hello friends. Back in April I bought five hens. What do you know four of them turned out to be roosters. There has been bloodshed so I had to move one rooster and one hen to my not yet complete chicken tractor. Not complete because there is no coop. The've done fine with just a roost and a tarp tossed over the top so far. The next few nights are supposed to be really cold. Should I do more or do you all think my current setup is sufficient ?

They will do fine even out side mine have been out in 0% no problems .
That is what I keep my roosters in just about what you have.

Thanks Jimmy. We rarely get single digits here so I just wanted to make sure. Thanks again.

The only thing I've done with mine is to make sure that they are protected from the prevailing wind and moisture from above, also that they have fresh air - and mine were in -15 to -20F for a bit in November and December. I think your set up will work just fine for the weather you are likely to have down there. Mine are really loving being protected by the two feet of snow we got last weekend.

I'm am in a similar winter climate and have my chickens in a similar setup. Like bill, I have blocked the north wind and the top of their roosts. I used a tarp to do so. In previous roost setups I have also made a wind break with square bails to block wind. The Chickens do not mind one bit, and will actually come out and forage while it is freezing rain or snowing.
I have heard certain breeds with a big comb will get frost bite on it. None of my hens have a comb, but my rooster does, and he hasn't had any frost bite trouble yet.

Thanks for all the chicken knowledge. They seem to be creatures of habit. Since my photo I've put a cozy coop for two in the run. Neither will have any part of it. They still sleep on the end of a barely protected roost.
