I feel your pain! Several years ago we started out with 6 RIR's that we obtained for free and built them an A-frame. Of course the next year we had to have a few more, then a few more, then we met someone with an incubator..and a few more. This past year we had 24 hens and one rooster. We couldn't keep up with egg orders so I ordered more chicks, and sold off some of the non-productive older hens. I raised up 30 new chicks this Spring and kept just 2 from the past year.
Then all heck broke loose. We had an unusually cold, rainy Spring (well, no Spring at all!), both DH and I needed to find new employment due to layoffs pending with our employer, our DD decided to do a semester out of state for summer school, and a number of serious home repairs became absolute necessities NOW. I had also had to euthanize 3 hens in the last few months, felt like every day when I went to collect eggs that I would find yet another disaster. Oh, and the coop needs a new roof as it is leaking now...into the nest boxes. And we had increased the size of the flock to the point that no one was allowed to go out to the coop unless they turned on the hose to fill waterers and took the hand cart to bring another sack of feed to the coop.
So, I sat down with my daughter to discuss the options. I no longer felt enjoyment from the chicken venture and she was leaving for summer school. Even her Fall schedule would leave her little time to help. Our egg customers are very nice people but have gotten used to only paying $2/dozen (and it didn't seem that they were willing to pay more) and they like to have their eggs delivered. They were not all timely with remembering to leave their payment for eggs on their delivery days, many falling several weeks behind in payment, me needing to email reminders regularly. I have a full time job and it isn't about chickens. I don't need another job! Then with the increase in feed prices and gas for the car to make deliveries, new schedules with new jobs, DD not going to be here to help...end result was that we decided to downsize the flock to just 4 pet birds. We are going to keep the equipment (feeders, waterers, brooding pens, etc) for now. You never know, I might want to do it again some day. And there's plenty of storage in the coop shed now that it's empty.
The last of the pullet flock left last weekend and we are down to 1 silkie, 1 gamebird, 1 Jersey giant, and I kept one RSL pullet mainly for eggs for us. I couldn't be happier. They are back in the original A-frame coop. I closed up the doors of the leaky, mouse infested coop shed and I'll deal with that when I have more time and patience. We sent emails to our egg customers letting them know ahead of time. And I now enjoy knowing each chicken by name again (not the leg band number that was color coded to the year they were hatched!), I unfold the lawn chair again just to sit and watch them, a bowl of kitchen scraps lasts them for days (we've actually started putting some kitchen scraps in the compost pile again because we have too much), and I am at peace.
If you decide to downsize I don't think you will have any problems finding good homes for your birds at prices that should reimburse you for the food and effort put into raising the birds. I had posted my birds for sale over a month ago and I'm still getting 3-4 emails per week asking for birds.
Whatever you decide will be the right decision for you. Everyone should be at peace with their home and life. Take the time to listen to your heart and you will know what is the best choice for you.
