I had 2 mature Welsummers and then acquired 3 in-lay Warrens. They were kept in adjacent, very nice pens and houses for a few days, before merging them into one small flock. Before the merger they had all slept in their chicken houses and for a few days after the merger, they put themselves to bed all together in one house - as one would expect. Then the trouble started! We had a period of very hot weather and since then they absolutely refuse to go into the house at dusk, sleeping outside in the run. This is still the case, despite the fact that the weather is now cooler. Now I know you are thinking "red-mite"! However I am convinced this is not the problem because prior to the chickens being put in the house, it had been left empty since last September, had been emptied and disinfected 4 months ago and then left empty until this new lot of chickens were put in there. So I am at a loss to know what to do or what is the cause of the strange behaviour. My husband and I have to go out each evening at dusk and catch them and put them to bed, but I do not fancy doing that much longer. However, once it gets cold, they will be very miserable if they stay outside. Any ideas what can be the problem? Or ideas on what I can do to persuade them to use the chicken house.
For one, I always quarantine new chicks and especially adult birds for 2 months...they recommend atleast 2-4 weeks, longer is better.
Now for the going to bed issue...it might be, that the new chickens and the established flock are either not getting along, have not established a pecking order, or HAVE established a pecking order and said nope, you aint comin in...you didn't say if all your chickens are outside, or if it is just the new ones...so this is incase it's the new ones only.
Another reason, if it is all the chickens, new and old, once something is imprinted in their little brains, say...my coop is too hot, run is cooler..then that imprint will stay, until someone, like you and your hubby, change it and get them to realize it is not too hot...I have read people doing what you all are doing for 2-4 weeks, every night before the chickens "got it".
What I do, but remember, mine I raised all from chicks and they are only about 2 months now, so they think I am Mamma chicken...don't laugh now, well if you do, enjoy the laugh
Come dusk, I go in the coop and "cluck" them in. I had them out for a couple hours, before our run was done, and it got near dusk and no one was going in,( no matter what I tried) so I went in their coop, and stayed where they couldn't see me and clucked like a Momma chicken would, to call the chicks in. It worked that time.
Well our run is done, so they have had two days in that. All new, a ramp, first time, a little pop door, all new and even though they had been running up the ramp, peeking in the pop door all day, then launching themselves off the top of the ramp, do you think those buggers would come in? My main cockerel got some in, but the others stood in the run and hollered. I only got the cockerel to get the ones in by moving where I could see them, but they could not see me. Well here I go again...back into the coop, head stuck out the pop door, barely, and clucked, they answered, and one came to the end of the ramp..so I pulled in my head, clucked again, she answered and sounded a little closer...well, got her in, so kept this whole shenanigan up till I had, once again, clucked them all in and ran and dropped the pop door before someone decided to go back out. Today they didn't go out, as it is pouring rain, and they are just getting over cocci. So hoping I have implanted what they have to do, if not, a cluckin I will go again. I can not, at my age, catch them and have no help...this idea was born out of desperation and even surprised me, that it worked.
No idea if it will work for you, and I would bet your husband will be on the ground laughing, if you try it ( which could really distract the chickens from you and the task at hand )..but it IS worth a try! ( and ask hubby to please, if he has to die laughing, do it somewhere wayyy away from the chickens) Better than chasing them, if it works. I don't know how your new ones will do, but if you raised the others from chicks, it could work on them and maybe, if the others see them go in..they might be interested and curious enough, to check out what this whole thing is about? Also, it took some time, they didn't come right away, I had to "talk" to them, cluck, have them answer back for a while...I bet it took ateast 20 mins to half hour to get the last of them up the ramp and in!
Good luck!!!!
Good luck and know, I did check, the first time I did this, to make sure no one was around to see or hear me...LOL
