Suprelorin implant : experiences when the effect wears off ?

[ManueB]

Short question : has anyone had a hen start laying again a few eggs once the implant wears off, then stop ?

Longer story:
Our hen Laure was implanted on the 17 august 2024 , at only 15 months old.
She had been laying soft shells or shell-less eggs very painfully for a month and we were worried about a risk of peritonitis. We heard from the vet and from other chicken keepers that sometimes an implant can get the laying system back on track, when there is no real issue beyond the shell making, and so we were hoping this would be her case.

After more or less five months, on the 25 of January she laid a first egg, totally fine.
On the 2d February she laid a soft shell egg. I made an appointment to get her reimplanted.
On the 5 and 8, she laid an egg with a little cap, then a perfect egg.
But since then, she hasn't laid at all and it's been twelve days now. I've already postponed the vet appointment once and I'm hesitant to postpone it again. I don't want to get her implanted her again if she doesn't need it.

Has anyone had a similar experience ?
I will eventually contact the vet to ask her about it if I postpone the appointment once more.

Thank you for reading and for your help.

I have read where they can last 4-6 months, but I have no experience with them. But some hens with reproductive problems can stop laying eventually on their own. Also in winter months, laying can stop due to having fewer hours of daylight. I hope that your hen does well.

Yes, I do have another hen that stopped laying a year ago, when she was not even two, after two months laying strange eggs. But I don't think that's Laure's case, because the rooster is mating her, and he is usually very good at knowing which hens are laying or about to.

I will update on how things turn out for her, in case something similar happens to someone else's hen. For now she's doing very good !

Does your hen showing signs that she is still laying?
Like bright red comb, the width of her vent, and space between the 2 pin bones?

Does she go to the nestbox as if she is laying egg, but no egg?

Check her tummy size and temperature? Is it bigger or warmer compare to your other hens?

Here is an article about is your chicken laying?

You could ask your Vet, have her check out at the Vet to find out if she is laying or not.

You could email the British Hen Welfare ask them.
They rescued production egg layer chickens, rehome, give them implants.

My personal experience with implant:
I have 1 of my Isa Brown on 3rd implant now.
1st implant - it was effective for 4 month
2nd implant - it was effective for 2 months.
3rd implant early this February, she stopped laying egg on 2nd day of the implant.
My hen here is an old girl 4 years old and once the implant wore off she was back laying eggs, at first just a few eggs, then 7 massive eggs a week. These happened on both her earlier 2 implants.

I am wishing you all the best with your little hen.

After laying 4 eggs and taking 17 days of pause, Laure laid two eggs, one on tuesday and one yesterday, both perfectly normal.

All the signs you mentioned had been pointing to her laying, except she wasn't.

I suppose this 17 days of break is a curious side effect of the implant. Before she began laying soft shell eggs last summer, she was laying three eggs a week, so i'm expecting something like this again if all goes well.

Thanks for telling me about how things went for your ISA. For a red hybrid, she's already indeed an old lady at four and I hope the implant helps her get some more time with you.

It does seem that every hen responds slightly differently to those hormonal implants. The first month and the molt was extremely hard for Laure, I was actually beginning to think about bringing her back to the vet to have it taken off the day before she started feeling a bit better. This is why if we don't have to reimplant her, I would rather avoid it !

I'll update in a few weeks once we can tell if she really has no issues laying anymore, or not.

I am so glad your little Laure is feeling better. You are right, each hen responded differently to the implant.

Perhaps the 17 days break is her body is responding to the implant. I imagine like the implant is effective in those 17 days hence egg break, then it weakens by how her body processes it, and so she laid 2 eggs after. This is how Laure's body reacting to the implant.

There are 2 size of implant, 4.7 and 9.4mg. The Vet I went to only do the 4.7

Thank you, please do update. Implant for chickens is new, and there are not much data on this.
