Housing what is recommended?

See that one came out OK. poults in there are two weeks old, under two eco brooders when they need some warmth, which hasn't been often of late, also see on previous photo that carpet roll was left down today due to storm going through.

I have seen this on ebay and can't see how it can house 15 birds?

I am looking at getting maybe 3/4 was thinking ex bats. Would this house be suitable? What would you say the max would be for it?

Many thanks.

the second link doesn't work for me. As for the first the design looks ok at a first glance, however I would want to know the thickness of the wood and also what it has been treated with and how long this treatment will last.
Layers are built differently to meat birds and have very little meat on them - you can get utility breeds where you keep the hens for their eggs and eat the cockerels, however these are pure breeds so the cockerels mature slower than meat birds so they may be crowing before you cull them.

the asphalt roof could be a great hiding place for red mites unless it is glued down with tar
On average a large fowl will need 12 inches of perching space each, the makers claim they will house 12 small or bantams so really only 8 large fowl at the most.
The first one states that it is big enough for 15 birds well I think they would be rather crowded unless some decide to sleep in the nest boxes. Also you really dont need that many nest boxes, you only need 1 per 3 birds at the most.

I don't want any boys as not sure the neighbours would like it so looks like it will be egg layers and possibly some dual birds to eat can they go in with each other? I know someone earlier said that meat birds need different things but not sure if duel birds do? Sorry for all of the questions.

joyful would you recommend the first link then depending on thickness etc? I will ask the seller. What would you say would be the right/ideal thickness of wood? What should I avoid for treatment of the wood?

Thanks again xxx
