Have any pics of your heat tape setup youd like to share? Thanks

Hi,

No I did not take pictures. But it was not our idea. Got the information from Craig Hopkins website.
But do want to also add pay close attention to the temperature of the perch. I also wonder if there was some malfunction in the tape. We had a incident last year and it burned a few birds feet severely. This happened with one perch.
That was a real surprise. You try to keep them warm and safe then that.

I guess I wont be getting any after all. There is no way they are going to have a heated coop or perches with me. I'll have to stick with the blues.

You could get pieds.

Excellent point. Or 50% spaldings. Still nice and then you would not need to worry. And I have heard from others who keep 75% in no heat or no heated perches. Some have said they put a thick layer of straw down and the birds get in and keep warm enough.

Yeah maybe it could work if you had a small shed that was well insulated and the birds could just stay in there. All they might need is just a really wide perch so they can lay on their feet. That is the main thing is you want their feet to be warm.

This is what happens when they don't have enough heat (notice the feet):

I am not totally sure if that is the reason that the peacock is missing half of every toe on his feet but I would guess more than likely that is the case. I came across the pictures on Zoochat one day and was saddened to see the poor thing with his bad feet.

A hybrid between two different species (the spalding) and a

It's not the same thing !

"The Indian Blue (IB) and the various Green peafowl are different
species. There are many genes different between them. When you cross
the two, the first generation offspring (the F1) will be more or less
uniformly intermediate between the two. They will have a bluish-green
turquoise-teal coloration on the neck, display intermediate wing
patterns, etc. This is because they are 50% IB and 50% Green by
heritage -- half their genes come from the Blue species and half from
the Green species (parents each give 50% of their genes to offspring,
and in this cross, one parent was IB and the other was Green). Anyone
who tells you that the F1 50% hybrids between two pure species will
also vary among siblings is incorrect -- this happens ONLY when either
the IB parent or the Green parent is impure itself, which is actually
very likely among peafowl in the US today. But that's another topic
entirely.

If you took this 50% offspring and bred it back to a Green, the next
generation will be said to be 75% Green, because in its ancestry, one
grand-parent was IB (thus 25% IB) and three grand-parents were Green
(thus 75% Green). Each grand-parent contributes 25% of its genes to
its grand-offspring.

These percentages of species heritage are reliable indicators of
general appearance ONLY when breeding a hybrid (Spalding) back to a
pure species. When breeding a hybrid to a hybrid (Spalding X
Spalding), the percentages mean little because while offspring may be
50% Green by heritage, it may look more IB or more Green if its
parents were both 50% Green. This is because hybrid parents contain a
mix of genes from both species, and while each will contribute 50% of
its genes to its offspring, it will be at random what mix of
chromosomes go into the sperm or egg.

Let's imagine we have an F1 50% Spalding peacock (male). Its mother
was an IB and its father was a Green. It inherited one of each
chromosome from its IB mother and the other of each chromosome from
its Green father. In its cells, its chromosome pairs are made up of
one from each species. When this male makes sperm, it will be at
random which member of each pair of chromosomes will be in each sperm.
It's possible that one sperm could have all the IB chromosomes from
its mother, and it's possible that another sperm could have all the
Green chromosomes from its father, but that's very unlikely.

Chromosomes also cross over during meiosis (exchanging parts with the
other member of the pair, forming newly combined chromosomes), so it's
possible to have chromosomes that are individually a mix of both
species. And it's much more likely that sperm will contain a random
mix of IB and Green chromosomes.

So offspring from a 50% Spalding male could get mostly IB genes from
its dad, mostly Green genes from its dad, or something in-between. If
its mom was also a 50% Spalding, we could see a range of appearance in
offspring from 50% Spalding X 50% Spalding that could range from
looking very similar to an IB or looking very similar to a pure Green
(these would be in the minority), and most that range somewhere in the
middle.

This is all different from breeding hybrid genotypes. For example, if
you crossed a normal IB male with a Bronze female, the difference in
appearance between the two colors is due to just one gene (unlike the
many, many genes that are different between IB and Green peafowl).

In species-hybrids, the percentage refers to the ancestral
contribution from each species. A 75% green Spalding will have 3
grand-parents that were Green, and one that was Blue. All of its
siblings from the same ancestors will also be 75% green by heritage.

In genotype-hybrids, the percentages refer to the probabilities of the
genotype occurring. So the 1:2:1 ratio says that in a mating of IB
split to Bronze X IB split to Bronze, offspring have a 25% chance of
being Bronze, 50% chance of being IB split to Bronze, and 25% chance
of being IB and not carrying the Bronze gene at all."

Conclusion: spalding I made this year are F1 or Spalding 50%.
If they are spladings 50% they will resist the cold.
