well i am still waiting on our chicks. LOOOONG story.... so i can't say anything about having them BUT -
my DH gave me about 6 hours notice to decide to get them or not. We live out in the 'country' so there's about 2 acres on either side of us or more before we have any neighbors. We have all types of wildlife out there (this past winter we had our first bear HUGE!) so i was and still am concerned about predators. But I think our coop will be just fine! I realize if animals are hungry enough they'll do what they can to get in so nothing is ever predator proof but we've done pretty well. (i will have to post pics later)
Also, we decided we will not be eating them (we're getting 12) so we don't have to worry about that but i have to say that since we decided to get them, i'm excited. I know it's going to be work but i've read so many things on this site that make me look forward to it more. Our delivery date has been moved 3 times now so the anticipation is increasing. We've decided since our house is small and our dog doesn't love animals smaller than him; we will be keeping the brooder box in the coop with heat lamp. that way they're safe all the way around. I think if you are able to have them, are willing to take the time and WANT them, they will be nice to have. that perhaps doesn't answer your question. and with any luck, we'll have the chicks next friday so i may be more assistance then.... Hope that was at least a little help.
