Because I'm trying to go with FREE first. lol. I have a ton of $$ in these chickens and now we're about to start a coop expansion that will probably cost a couple hundred more at least, so I'm trying to save money. If it comes to that I will go ahead and save up for a real plant but dh said to go ahead and put the wild grapevine there since it's way out by the grain bins and not by the house anyway. We figured the chickens would keep it maintained. The ones by the a/c are coming right out of the concrete (probably a crack, I'm guessing) but I found one growing in the yard so I dug it up and planted it in a pot for now. If it lives and gets bigger I'll plant it outside the run.
The 3 mulberry trees we've tried aren't doing well. One we put right in the run with a fence around it and it looks totally dead. I planted 2 in pots and they don't look so good either. The funny thing is, we can't kill the darn things when they're growing wild in the yard but I can't make one grow where I want it.
